How to clone a server without downtime and with the exact same app domain as before? about caprover HOT 1 CLOSED

I went ahead, trusted my gut and used a different than usual solution which worked flawlessly (atleast so far). To use this solution one must have a floating/reserved ip at their hosting service (in my case digital ocean). Here are the steps:

1. Took my backup from the existing droplet
2. Created a new droplet with Ubuntu 22.04 (it assigned a random new ip to this droplet)
3. SSH'ed into the droplet with the new IP and installed the latest Docker, then allowed the ports as in instructions
4. Followed instructions in caprover docs to copy the backup to the caprover directory
5. At this stage I simply changed the floating/reserved IP to point to the new droplet from the old one (downtime started). I intentionally changed the IP BEFORE the caprover restore so that there's no issues with swarms or anything.

The following steps were done quickly to limit downtime:
6) I now SSH'ed from my reserved IP, and when it connected it showed the new server name, so the ip address change was successful
7) Ran the command in the instructions to restore backup (Instructions:https://caprover.com/docs/backup-and-restore.html)
8) Quickly re-pushed my code and since the IP (and hence the domain) was already pointed to the new droplet, the webhook deployed on the new droplet automatically.

All in all, the app was down for 3-4 minutes and there are absolutely no DNS or SSL issues. SSL was working out of the box as well.

Thank you so much for this amazing platform and thank you for the backup and restore feature.

I wrote the above answer so maybe it can help someone in the future!!
