GxP Data Migration Validation: Strategy, Reconciliation and Evidence sets the general reconciliation method for any regulated migration and warns against describing transformed historical information as a native target audit trail. This reference answers the more specific, Vault-technical question that method leaves open: what actually happens to version numbers, audit entries and workflow history when content is loaded into Vault by Vault Loader or the API rather than created through the normal user interface, and what evidence should exist afterwards to show that history was preserved, or deliberately not preserved natively, rather than quietly conflated with it.

Choose a version-preservation strategy before migrating a single document

Vault gives a migration team a genuine choice about how much of a document's prior version history becomes native Vault history, and that choice needs to be made and documented deliberately, not left as an accidental side effect of how the load happens to be built.

Current-version-only. Load only the document's current content, and use Document Migration Mode to set its version number to match the source system's true current version, for example loading a document straight in as version 1.4 rather than forcing it through versions 1.1 to 1.3 first. This is operationally simpler than recreating the complete historical-version set, but it preserves a label, not content: versions 1.1 to 1.3 do not exist in Vault, cannot be opened, compared or retrieved through Vault after migration, and any question that needs the actual prior content, not just the fact that three prior versions existed, cannot be answered from Vault alone.

Full historical-version load. Use Vault Loader's Add Document Versions action, selecting Document Versions as the object type and Create as the action type, to load each historical version's own content and metadata as a genuine Vault document version. Done correctly, this produces a real, browsable version history inside Vault: version 1.1 is an actual retrievable document, not a number. This is the only one of the three strategies where "the version history is preserved" is true at the level of native Vault content, and it is the appropriate choice where prior version content itself, not merely the version count, remains relevant to an ongoing regulated decision.

Legacy history as labelled external data. Do not attempt to recreate prior versions or audit-trail entries as native Vault objects at all. Instead hold the historic information as clearly labelled migrated data, addressed in detail below.

Pick one strategy per document population, or per document type where different types warrant different treatment, and record which strategy was applied and why. Do not let a mix of ad hoc individual decisions during load stand in for that documented choice: a migrated record that displays a plausible-looking version 1.4 with no record of whether that reflects current-version-only loading or a full historical load is a gap either way, because a reviewer cannot tell which claim the record is actually entitled to support.

Confirm the load itself is captured, and know what it actually proves

A common assumption is that documents or records loaded through Vault Loader or the API arrive in Vault with no trace of the load having happened. Vault's own documentation on how object record modifications are tracked states that record creation, modification and deletion are captured in the Object Record Audit History as a matter of how the platform works, and Vault's document audit-event documentation covers the equivalent capture for documents; neither describes an exemption for records or documents created or changed through Vault Loader or the API rather than the user interface. Treat this as the platform's default behaviour to be confirmed for the organisation's own Vault release and configuration, not as an unverifiable assumption in either direction.

What that native load-event entry proves is narrower than it looks, and this holds regardless of which version-preservation strategy was chosen. It proves that a load action occurred, by which user or service account, and when. It does not, by itself, indicate which version-preservation strategy was used for that record, and it does not retroactively create the approval or review events that happened in the source system before migration. Confirm the load event separately from confirming which version-preservation strategy applies; they are different questions with different evidence.

Where the full historical-version load strategy is used, also confirm, rather than assume, whether the resulting audit-trail entries for those historical versions reflect the original source system's creation dates and identities or the migration load event's own date and service account. Vault's version content becomes genuinely native either way, but if the audit trail itself needs to show original historical dates and users, that may still require the labelled-legacy-data treatment described below for the audit trail specifically, even where full version content has been loaded natively.

Keep the legacy history as data, not as an impersonated Vault audit trail

Where a legacy system's own audit trail needs to survive the migration, for example because a record's change history remains relevant to an ongoing regulated decision, and particularly where the chosen version-preservation strategy does not itself recreate that history natively, bring it across as clearly labelled migrated data rather than attempting to make it appear as native Vault audit-trail entries. A practical pattern is to hold historic audit information in a dedicated object, with its own attachments where the volume warrants it, explicitly named and described as legacy history imported from the source system, including the source system's identity, the export date and the person or process that performed the import.

This matters because a reviewer or inspector examining Vault's native Document or Object Audit History should be able to tell, without ambiguity, which entries describe events that actually happened inside Vault, load included, and which are migrated representations of events that happened somewhere else before Vault existed for that record.

Represent workflow and approval history honestly

Records that were approved, reviewed or routed through a workflow in the legacy system before migration did not go through Vault's own workflow engine, and Vault has no native workflow task history to show for that prior process, regardless of which version-preservation strategy was used for the document content itself. Do not attempt to recreate artificial workflow tasks in Vault purely to make a record look as though it was approved inside Vault; that misrepresents what actually happened and can make a genuinely approved legacy record look like it went through a Vault process it never did.

Instead, represent the prior approval or review as migrated evidence, referencing whatever legacy approval record, signature or minutes actually exist, and keep it visibly distinct from any approval or review that happens inside Vault going forward. Where a migrated record still requires an approval step that Vault itself will govern from this point on, that step should run as a genuine Vault workflow producing its own native history, not as a formality layered on top of a fabricated migrated one.

Reconcile the migrated population against the chosen strategy

Reconciliation evidence has to match the strategy actually used, because each strategy makes a different claim.

For current-version-only migration, reconcile that the assigned version number matches the source system's true current version number for every migrated document; a mismatch here means the label itself is wrong, not just incomplete.

For a full historical-version load, reconcile the expected count, identity and sequence of versions for every migrated document, and verify source-to-target content and critical metadata using a risk-based method appropriate to the population. Representative sampling may supplement that verification, but should not substitute for deterministic reconciliation where the migration tooling can perform it.

For legacy history held as separate data, reconcile the completeness of the imported history population, no records silently dropped from the dataset, and confirm the labelling clearly identifies it as migrated data rather than native history.

For every strategy, additionally confirm the presence of a native load-event audit entry for every migrated document or record. Veeva's own migration guidance notes that migrating large volumes of legacy audit trail can materially affect load time and performance, which is itself a reason this reconciliation needs to be planned and resourced deliberately rather than treated as an afterthought once the substantive content migration is done.
