Migrating from M365 Exchange to Google

UD faculty, staff and students who use the UD Exchange system for email and calendaring may need to migrate to Google. Typical reasons for migration include losing access to M365 because of retirement or graduation, ending student employment, or working for a department that requires Google use.

You can use the Microsoft Exchange Account Migration to Google form to request an account migration. 

Note that those who leave UD prior to retirement or graduation are not entitled to retain a UD Google account.

General information

• Exchange accounts for retirees and students should be migrated to Google on or prior to the last date of employment or before graduation.
• Exchange email will be migrated to GMail. 
• Calendar migration will be attempted but is not guaranteed. If it fails and calendar information is needed, the calendar must be manually exported from Exchange and migrated to Google.
• Contacts cannot be migrated.
• After your account has migrated, you will no longer be able to access shared calendars on the UD Exchange system, and you will no longer be able to access calendars in Microsoft Teams. 
• Partial migrations are not currently possible. When an account migrates, all email will move to GMail.
• Migrations must be scheduled when UD is open the next day so that assistance is available, if need be. 
• Migrations are run in the evenings, Sunday through Thursday.
• Accounts will not be migrated the evening before a holiday break.
• A one day lead time is required for migrations.

Before the migration

• Delete all unneeded messages, and empty the Deleted Items folder. 
• Check the space in your UD Google account to make sure there is enough room for your migrated account. Keep in mind that alumni will have a 15GB Google account limit after migration, and retirees will have a 50GB Google storage limit after retiring. 
• After your account has migrated to Google, you will lose access to all Exchange shared calendars, public folders, shared mailboxes, and resource mailboxes that you can currently access.

During the migration

• Ideally, you should be logged out of your Exchange account when the migration starts, and devices that access your Exchange account should be turned off. 
• When the migration starts, you can receive and send email at https://googleapps.udel.edu. 
• Do not move email messages in your Google or Exchange accounts until after your account has fully migrated.
• Account migrations can take a long time, even days, because Google throttles data transfers. UD cannot control the migration speed.
• If you don’t see all your messages in Google within a day or two after the migration starts, contact the IT Support Center to check the status of your migration.

After the migration

• Make sure your Google account does not exceed your current or anticipated storage limit (i.e. if you are going from active employee to retiree). You will need to delete enough data to stay under the max storage limit for your UD affiliation. 
• Remove your Exchange account from your computers and devices. Retirees and alumni are no longer licensed for Microsoft Office through UD, and you should delete Microsoft Office from your computers and devices.
• Use a web browser to access your migrated account at https://googleapps.udel.edu. You can also add your UD Google account to mobile devices.
