Customize Your Migration By Using A Multi-Pass Strategy

Conducting a multi-pass migration consists of pre-staging a majority of the data in each mailbox prior to a cut-over and following up with a delta pass to pick up all the residual messages. This type of migration can be beneficial in migration projects working with low-bandwidth and those that would like to mitigate some of the risk associated with other types of migrations.

There are two ways to conduct a multi-pass migration to fit the needs of your organization. You can set up mailboxes prior to a cut-over to contain all the messages from the last month, three months, etc. This will allow your users to have instant access to their data after the cut-over and then the migration team can follow-up with a delta pass to move older messages after the MX records are changed.

Another popular multi-pass technique allows you to pre-stage your data and move all of the messages that are older than two months, six months, etc. prior to the cut-over. The migration team can then follow-up with a delta pass that will pick up the recent messages prior to changing the MX records and your users will have all of their information populated in their new messaging system on day one.

Conducting a multi-pass migration with MigrationWiz is a breeze. Using a premium license you get ten passes per mailbox to complete your migration. Our web-based interface allows you to easily initiate an additional pass on a mailbox after our tool has detected which messages have been moved and excludes them from the migration to eliminate duplicate messages in the destination system.
