The client engaged TrueSwift to provide a managed extraction of legacy mailbox archive messages from their Enterprise Vault (EV) environment to Office 365 and to PST files.
The use of the TrueSwift Migration Factory environment was contracted and ~12TB of compressed EV data was shipped to TrueSwift loaded on to a NAS, which in turn was connected to the Migration Factory application server.
The project was run as 2 phases, with the first phase being a small 24 user archive pilot and the second phase containing the remainder of the EV system data consisting of 9,064 archives.
The production migration to Office 365 was carried out in batches of users, supplied to us by the client on regular intervals which coincided with the client’s user mailbox migration to Office 365. This resulted in the user having access to their EV archived data placed in to the Office 365 Personal archive, shortly after their mailbox had been transferred to Office 365 by another one of the client’s internal project.
The migration of EV data to Office 365 was only carried out for current users, with the remainder of EV data archives being migrated out to PST files.
The PST files were created with a 5GB size limit and therefore archives greater than 5GB in size migrated to multiple PST files. All of the PST data created was split by user and copied to a NAS, which was shipped back to the customer.
The engagement was hosted in the TrueSwift Data Centre and utilised the TrueSwift Migration Factory environment.
Weekly Webex calls were held with the client to keep them up to date with progress and any issues.
