How to run 2 duplicated cPanel Accounts simultaneously

Hi There,

I had recently migrated my cPanel to Digital Ocean. But once the DO cPanel is activated, my old hosting cPanel is either getting suspended automatically or the A records (Host IP Address) of my Private Nameservers are modified and pointing to DO automatically without me changing them.

So, my question is - Is there any possibility to activate both the cPanel accounts and run simultaneously - so that I can shift the servers anytime any error occurs - from DO to my old host (or Vice-Versa) just by changing the A Records (Host IP Address) of my private nameservers?

All my websites on the account are purely WordPress Built and no emails hosted on the server.

Also, as I recently migrated to DO - I just want to check just 1 or 2 sites of my whole account by pointing them to DO and leave the remaining pointing my Old Host. So for this testing purpose - how can I proceed? Once I’m happy and everything works fine, then I can change the A Records directly and point the whole account to run from DO Servers.
