Hello Team,
One of our customers requirement is to migrate existing GroupWise messaging system to Office365 with minimum interruption & losing the data since the nature of their business is very critical, we can't afford to lose any single message during the migration.
Customer is having around 500 user mailboxes.
The challenge is here how to migrate 500 mailbox in single shot (cutover ) migration and reconfigure all 500 user's profiles to O365. I am trying to understand is there any way we can have a hybrid (Groupwise & O365) both running and we can migrate the user mailboxes in batches which is very controlled way of migration.
I need your support in order to understand and gauge the migration challenges.
Appreciate any help or step by step documentation of complete migration process.
Thanks in advance,
Abul.

Hi @Abul Fazal
Generally a hybrid environment is working with existing on-premises Exchange organization to the cloud.
And the original method provided by Microsoft to migrate from a 3rd party email system to O365 is using IMAP migration (you need to make sure your source email system support IMAP migration) or Use the Import Service to migrate PST files
Details can be found here:
Use the Import Service to migrate PST files
Migrate email from another IMAP-enabled email system
And the official also introduces the way with 3rd party migration, There are many tools available from third parties. They use distinctive protocols and approaches to conduct email migrations from email platforms like IBM Lotus Notes and Novell GroupWise.
Quest: Provider of migration solutions from Exchange, Microsoft 365, Office 365, Gmail, GroupWise, Notes, POP/IMAP, Zimbra, Sun ONE/iPlanet, PSTs and email archives to Microsoft 365 or Office 365 and Exchange. Quest solutions synchronize mailboxes, public folders and calendar information while maintaining coexistence throughout the migration.
