Regular performance problems, user access problems, error messages, longer downtime to mailboxes, database crashes are the most typical causes of issues.
Due to which companies choose to go for Office 365 Migration Services to migrate from Exchange versions. This can include getting the benefits of Azure VDI as well and working on Exchange in the era of cloud-based processes is not quite ideal.
Selecting the Appropriate Migration Method
The initial step required in the transfer is selecting the appropriate Office 365 migration method. There are various methods included in migration, and you need to determine the most suitable method that best fits your specifications.
Following are 4 migration methods to choose from:
Method 1: Cutover Migration
A cutover migration is a simple method created for small enterprises with data and mailboxes less than 1000. In this process, the migration is accelerated and takes place all at once, therefore called a ‘cutover’. At times, this method might not work properly even for small enterprises if the user mailboxes involved have extremely large and this may utilize more time than expected to finish the migration. This method can particularly be applied to Exchange Server and not when you Migrate SharePoint 2010 to SharePoint Online or any other type of migration.
Method 2: Staged Migration
A staged migration is created for mid-sized enterprises. This migration process is used to transfer users and mailboxes from on-premises Exchange versions and Exchange Online. This method transfers the mailboxes to Office 365 but consumes a little more time. Once it is finished, you get the hosted mailboxes on Office 365.
Method 3: IMAP Migration:
This migration process is applied when a non-Exchange mail system is present. IMAP migrations have the potential of moving e-mail messages only. But calendars, contacts, and tasks are missed through the process. This method is often used as a shortcut to be transferring from the earlier versions of Exchange Server to the cloud.
Method 4: Hybrid Migration
The process of hybrid migration is the most adaptable method and also a difficult one. This method is generally used by large enterprises. In this method, the Exchange admin generates a hybrid Exchange Server deployment by building a link between Office 365 local and Exchange Server. With this system, you can combine Exchange Servers with Office 365 and also the current Active Directory.
While selecting migration method there are a few elements to consider:
- Size of data to be moved.
- The current email system
- The existing version of your Exchange Server
- Time taken for the migration project.
- The number of objects to be moved.
- The cost of migration
It is essential to analyze your existing mailbox environment to be sure that the environment is working properly.
