1. Take stock of the tasksMigrating to Office 365 requires planning a large number of tasks that may include:
- The temporary use of a hybrid system during the transition. For example, some users and storage locations may remain with Exchange on site, while the rest of the data is moved to the cloud.
- Email archiving with encoding of the existing message formats
- Migration of the data contained in calendars and applications
2. Prepare for the migrationMoving to the cloud demands careful preparation.
- The data. This is the time to make decisions regarding what you want to keep and what should be archived, migrated, and deleted. For example, it’s possible to archive emails with a third party archiving tool, since transferring all the emails takes up a lot of space and users don’t consult the old messages very much.
- The network. Business networks are often too slow due to the multitude of users simultaneously working online. While moving to Office 365, it may be a good idea to set up a centrally managed global firewall solution to distribute the data traffic over external networks without jeopardizing security.
