This article explains the migration of a dedicated SendGrid IP or outbound email from one account to another. 

If you wish to perform this migration and the accounts are not connected as a parent or sub-user, the administrators of both accounts must provide their written consent to proceed with the migration request.

Things to Consider Before Migrating IPs from SendGrid

Suppose your domain maintains a high reputation and is associated with dedicated IPs with a similar high reputation. In that case, migration is beneficial as this shortens the time needed for ramp-up because the migrated IP would already be warmed up.

Make sure to understand the following points before migrating the IPs from Sendgrid:

• You can migrate only dedicated IPs. Shared IPs can’t be migrated because they are interconnected with multiple accounts or domains.
• Migration is beneficial only if you migrate IPs with a high domain reputation.
• Migration is a cut-off process. The SendGrid support team removes IPs from the client’s account and adds them to MoEngage’s Sendgrid account, so there will be short downtime during this period. Note that you can't use IPs from two different SendGrid accounts simultaneously.
• You can use domains or subdomains in parallel from n number of ESPs, vendors, or SendGrid accounts. Technically, this is not an issue, but it is not recommended.
• There is a downtime during the migration. This migration process requires coordination, meaning the DNS should be validated during or before the downtime. Ensure you are ready to send emails from MoEngage right after migrating IPs. If you migrate IPs and then spend 2 to 3 weeks or more to get your first email sent from MoEngage, IPs would lose reputation by then.

Migrating IPs is a good option, only if the IP already has a high reputation and a good sending history for at least 3 months and is already ramped up.

• Migration does not offer any benefits if a new migrated IP has not undergone the ramp-up process.
• If you migrate an IP with a bad reputation and delivery issues, you need to spend a lot of time (at least 6-8 weeks) fixing them.

Migrate SendGrid IPs

The following steps explain the process of migrating SendGrid IPs from one account to another:

1. The admin of the account hosting the dedicated IP should send an email to SendGrid support requesting to migrate the IP to the new account. The email should contain:
   • The IP address to be migrated.
   • The account with which this IP is associated.
   • The account to which this IP is to be migrated.
2. The admin of the account receiving the dedicated IP should also send an email to SendGrid support confirming their willingness to accept the dedicated IP into their account. This email should also include the IP address in question and the account it is to be migrated.
3. After the SendGrid support team receives written permission from both account admins, they will proceed with the migration process. This may involve some downtime as IPs are moved between accounts.
4. You can include the preferred date when you want the migration to take place.
5. After the migration, SendGrid support team notifies both account admins that the process has been finalized and the dedicated IP is active in the new account.
