This guide describes how a Veritas Enterprise Vault Archive can be migrated to a Microsoft Exchange Archive Mailbox using the Simply Migrate Management Shell, while also rehydrating the Enterprise Vault shortcuts in each user's mailbox. This avoids duplication of data by not migrating data that has been successfully rehydrated.
To ensure that database connection strings and permissions have been correctly set, follow the steps outlined in the Post-Installation Guide.
Creating Rehydration / Migration Jobs
The cmdlets listed below allow you to create jobs that perform a rehydration of a user's mailbox shortcuts from Enterprise Vault, and migrate all other items from the users Enterprise Vault archive to their Exchange Mailbox or Online Archive. The rehydration job starts running as soon as the batch controller picks it up. Once all shortcuts have been found and rehydrated, the migration job automatically starts to filter out all the items found by the rehydration job.
You can manipulate thee jobs independently, tag them and report on them independently.
The rehydration job is separate from the migration job. It rehydrates all Enterprise Vault shortcuts in place in the user's mailbox, but is created in a PowerShell variable so it can be used later.
$rehydrationJob = New-SmJob -Source Exchange -SourceInput email@example.com -SourceOptions UseStream, Ex2016 -SourceEwsUrl (Get-SmDefaultO365EwsUrl) -SourceCredential $Credentials -RehydrationSource EnterpriseVault -Tags 'Mailbox rehydration' -Batchid 1
The migration job migrates a user's enterprise vault archive into their online archive in Exchange, but introduces the "-FilterByJob" parameter to filter out any items that have been rehydrated by the rehydration job.
