Pre-migration checklist for cPanel to cPanel migration
To ensure that the migration happens without any failures, our cPanel technicians follow a pre-migration checklist that covers all checks to be ensured before performing the migration. This include:
1. Connectivity between the two servers
The source and destination servers should be able to communicate with each other. The checks we do, include removing any firewall blocks and establishing SSH connectivity to the required port.
2. Compatibility of application versions and enabled modules
The destination server is installed and configured with cPanel/WHM, PHP/MySQL versions and settings, PHP modules, Apache version and modules, other custom software, etc. that are compatible with the ones in the source server, to avoid any site errors.
3. Disks and the partitions in the new server
Number of partitions and disk space availability is ensured in the destination server so as to map the data from the source server optimally and without causing any disk space errors.

4. IP address availability in new server
Every cPanel server would have a main shared IP and one or more dedicated IPs for some domains. We perform IP mapping from source to destination server to avoid IP wastage and to fulfill the requirement of sites.
5. Reseller account and addon domain list
There are different types of accounts in cPanel servers, such as reseller accounts which possess multiple accounts under them and Addon domains which are parked over ordinary domains. Making a list of these helps us to check and confirm them in the new server.
6. SSL certificates
SSL certificates are specific to the domains. We check and copy these SSL certificates to the new server to ensure SSL availability in the destination server too.
