What are some best practice guidelines for migrating from G Suite or Gmail?
Here is what you need to know about migrating from G Suite or Gmail:
- IMAP access needs to be enabled for all users. Follow the steps in the Turn POP and IMAP on and off for users article from Google.
- Contact and calendar services need to be turned on for all users. Follow the steps in the Control who can access Google services article from Google.
- If migrating from free Gmail or non-paid G Suite accounts:
- Regular non-paid G Suite or Gmail accounts do not have administrative credentials. For these types of accounts, the process is as follows:
- Follow the normal steps for project creation, and set Advanced Options.
- When it comes to the G Suite or Gmail side (either Source or Destination, depending on your migration scenario), add the SMTP email addresses into MigrationWiz.
- When you submit for a migration pass, the item status in MigrationWiz will change to "Waiting For User".
- At this point, the end user should log in to their G Suite or Gmail account, and look for an email with the following subject heading: "ACTION REQUIRED: Information required for your migration".
- This will contain a link next to Source or Destination (depending on your migration scenario).
- Once the link has been clicked on, the next page will state: "MigrationWiz would like to have offline access". Click the Allow button to proceed with the migration.
- The status in your MigrationWiz project will now change to "submitted", and the migration will continue in the normal manner.
Note: Without admin credentials, your account may be temporarily locked by Google. Read the How do I unlock a G Suite account? article for more informatoin.
- If migrating from G Suite for Business or Education, then enable OAuth administrative credentials to avoid Google lockouts and having to provide each end user's credentials. Read the Enable access to G Suite using OAuth 2.0 article for more information.
Note: When setting up the migration project, and choosing G Suite as either the Source or Destination, it is necessary to add all domains that will be migrating from, or to, G Suite. This means that if there are users in one project with domain names Sourcedomain.com and Destinationdomain.com, you must ensure that both of these are added under Your Domains, when setting up the project in MigrationWiz.
- Review how items are migrated to Exchange/Office 365:
- Read the How are folders mapped? article.
- Read the Why was my Sent Items folder not migrated to the correct folder at the destination? article for more information about applying folder re-mappings.
- Read the How are Google labels converted and migrated? article.
- Read the What calendars are migrated with my account? article.
- Read the How are Google contact groups migrated? article.
- Read the What options are available for migrating G Suite/Gmail suggested contacts? article to learn how to migrate G Suite/Gmail suggested contacts.
- Be aware of G Suite throttling when retrieving data. Google may lock your account for 24 hours if they consider that too much data has been retrieved from their servers in a given amount of time. MigrationWiz adjusts migration throughput accordingly but remains subject to those limits. Read the Bandwidth limits for accounts article from Google for more information.
- MigrationWiz does not have a limit for the length of a label name. However, G Suite Iimits the length of label names to 225 characters.
- G Suite calendar items can have multiple reminder notifications. For example, a calendar item can have three reminders: the first reminder at 30 minutes before the meeting, the second at 15 minutes before the meeting, and the third at 5 minutes before the meeting. In Office 365 and Outlook, calendar items have only one reminder; therefore, MigrationWiz will migrate only the first calendar reminder. In example, then, the only calendar reminder that will be migrated is the one that appears 30 minutes before the meeting.
- G Suite calendar item titles (subjects) that are over 255 characters will be truncated in Office 365. For example, a calendar item with a title that is 403 characters long will be cut down to 255 characters in Office 365.
