Cutover migration vs Hybrid Migration
The Cutover Migration Strategy
You migrate everybody over a weekend for example. Cutover Migration is the simplest to implement. You can migrate your mailboxes in a single pass migration or envisage a pre-staging strategy where you run multiple migration passes.
A cutover migration is, therefore, a strategy where the entire company is switched at the same time.
The Cutover Migration Benefits
- The fastest, simplest form of migration.
- Your users can start using the new mail system immediately.
- New emails are received in the target messaging system.
- Old emails are migrated in a single pass.
The Cutover Migration Considerations
You can combine your cutover migration with pre-staging if required.
In this case, during the days or weeks leading up to your cutover, you would migrate all emails up to a week or so ago along with calendars and contacts, then on the day of your cutover, you would run a quick delta pass to migrate the remaining items.
Staged Migration Strategy:
A staged migration allows you to migrate batches of mailboxes over a few weeks or months. This strategy is useful for migrations with large volumes of data (Large mailboxes or numerous mailboxes) and if you estimate that you won’t be able to do your migration over a single weekend.
Hosting providers offers you additional flexibility in your approach to a staged migration. For example, you could migrate the last six months of emails over a weekend and leave older emails and email archives to be migrated after cutover, explaining to users that their older emails will appear soon.
During the days or weeks leading up to your cutover, you would migrate all emails up to a week or so ago along with calendars and contacts, then on the day of your cutover, you would run a quick delta pass to migrate the remaining items.
