Migrate sites from Enhance cluster to another

vsmbg

Hey everyone,

As the control plane feature will not be available soon, I have to consider alternative options. Manually transferring the control panel's data to another server seems risky and requires too many hours of work.

So I decided to try a different approach - get a new license with a fresh new control panel server. Then provision a new server for the application role. The question is - how can I transfer the sites from the current Enhance cluster to the new one? There is an automatic transfer from cPanel and Plesk but nothing from Enhance.

On that cluster, I have around 30 sites each between 15GB and 20GB.

Has anyone done that? Any advice would be recommended.

This feature is scheduled to be included in the upcoming v12.1.0. For now, the best approach is to use rsync to transfer the /backups/*/backup-subvolume/ folder for each site to the new app server, then restore manually. This folder contains all the files, databases, and configurations.

With just 30 sites, it shouldn’t take too long. Here are a couple of handy commands to help during the process:

Search backups on the Enhance backup server:

grep target_db_name /backups/*/backup-subvolume/home/public_html/wp-config.php
 
or  

grep account_username /backups/*/backup-subvolume/home/.my.cnf


To restore the database file:

su username
mysql -u db_username -p database_name < your_backup.sql

Good luck!

cPFence Thanks, I know it will be in v12 but the server has to go in 7 days, so can't wait one more month or more.
30 sites doesn't sound like a lot but there is no commands to create the accounts, transfer the DNS records, mailboxes and etc. If I have to do everything manually it will be easier to write a Python script to send the requests and do it, but still will take a few days work.

Has anyone tried to migrate already used role server to another cluster? Maybe we just need to search in the docker containers where is something referring to the current license or CP IP.

cPFence Would restoring from backup be data only, or would it also manage account passwords? i.e. mysql/email account? I just wonder if this might be an option for some in a tricky situation.

No, moving the entire role to another cluster isn’t that straightforward. Also, writing a script for this one-time process will probably take longer than just handling the 30 sites manually. That said, if you think the script could be useful for future purposes, then it’s definitely worth doing.

Yeah, you’d have to handle it all manually , not fun!. Thankfully, we’re using a VM for the CP. I think Enhance should mention on their documentation site that a VM is recommended for the CP. It would save a lot of people from making this mistake and realizing it too late.
