Nowadays, more and more organizations are moving towards a cloud based environment from the on-premise emailing setup. But, looking for the best way to perform migration has been an area of interest for experts. Although, one cannot say that there is some bad way or a good way. It totally depends on the requirements of the organization which includes the size of the on-premise environment, a number of users to be migrated, the base messaging environment and some other aspects. So, we will be discussing multiple methods to migrate public folders from Exchange 2007 to Office 365 in this article. Users can choose the methods which best suits their requirements.
1. Cutover Migration – This process is used if an organization needs to transfer all mailboxes at once. This migration is suitable for the situation if the total number of mailboxes is less than 2000. Another aspect which matters is that the organization is using Microsoft Exchange 2013, 2010, 2007 or 2003.
2. Staged Migration – It is used to migrate mailboxes in a batch. This conversion process is advised to the users if the number of mailboxes which are to be migrated are more than 2000. This process is also apt for the conversion if the organization is using Exchange 2003 or 2007.
3. Hybrid Migration – This migration type is one of the smoothest of all the process but it is most complex as well. It enables organizations to maintain both on premises and online environment allow users to gradually migrate public folders from Exchange 2007 to Office 365. This technique should only be used if the organization is using Exchange 2010 or 2013 and the mailboxes are more than 2000 which is to be converted. The transfer process is carried out in small batches over the time.
4. IMAP based Migration – If the Exchange Server supports Internet Message Access Protocol (IMAP) then you can use this method to perform the conversion. Moreover, this method has some limitations such as it allows users to move items of inbox only. Other mailbox items which include contacts, calendars, tasks can’t be migrated. It doesn’t create a mailbox in Office 365, you have to first create a mailbox for each user before starting the migration process.
In this article, we are discussing the conversion of Microsoft Exchange 2007, so Hybrid Migration is not suitable for us. Next, the IMAP method is also out because of its limitations. So, we are left with both cutover and staged migration and here we are discussing the steps to perform the cutover migration.
Cutover Migration
Step 1 – Plan
Microsoft Exchange Deployment Assistant (EDA) is the best utility which guides for all migration scenarios.
Step 2 – Verify the Existing Setup
To perform this process, the Exchange 2007 should support Outlook Anywhere and Autodiscover. Use the guide generated in Step 1 to check that the existing setup is correct or not. Then use MS Remote Connectivity Analyzer to verify Outlook anywhere. Now, allocate all the required permissions to the mailboxes which are to be converted. If users will skip this step then the process to migrate public folder from Exchange 2007 to Office 365 will fail.
If the above process gives a warning message, then refer the guide and verify if any mistake is made.
Step 3 – Configure & Start Migration
Performing the above-mentioned steps will create the migration batch and will set its state to syncing. The time consumed to complete the entire process totally depends on the number of mailboxes and the amount of data.
Step 4 – Complete the Migration
When the process completes and all mailboxes are moved, then the selected recipient will get the report.
Note – There can be some DNS replication involved but you should keep running the batch for 72 hours to enable the replication process.
As the manual method have some limitations such as it is so time-consuming and complex. It requires some technical expertise who have some knowledge in this area as the whole task can be a tedious job for beginners.
