Unsuitable Data
Unsuitable data needs a different approach when migrating to the cloud. Traditionally archive migration vendors have favored journal explosion or journal splitting.
Why Journal Splitting or Journal Explosion Are Poor Solutions
Journal Explosion recreates all the emails to all the original message recipients as the data is migrated. This multiplies the data volumes significantly and requires more time to create and transfer so many copies to the cloud than normally anticipated.
Journal Splitting involves transferring the data to hundreds or even thousands of shared mailboxes.
