[WHMCS MIGRATION] What Is The Easiest & Fastest Way To Migrate WHMCS Installation

Hi,

What would be the easiest and fastest way to migrate WHMCS installation...under production.

Thanks

The easiest and fastest way would be to use virtualization, which allows you the easy (live) migration of containers or virtual machines. Since you are asking this question, you are probably not using virtualization - I would recommend to consider that.

The migration is no different from other website migrations. Simply install the new server and copy the web content + database. When you have a tested, working installation, you can continue with putting the old WHMCS installation into maintenance mode, synchronize all modified files (e.g. rsync) and import the current database.

If the server IP will change, you should set the TTL at your nameserver provider to the lowest value and wait until the current TTL has expired. Afterwards change the IP to the new server just before the switchover. You will also have to reissue the WHMCS license if your IP will be changed. Also think about third-party vendor licenses and IP whitelist of payment gateways.

Since some DNS resolvers do not respect the TTL, you could also install a reverse proxy on the old server so that all requests are forwarded to the new server. 

If the migration is well planned, the downtime will be minimal.

We use managed DNS so all we need to do is edit A record for pointing it to a new one.

So what we need to do is to install WHMCS with the new server and copy the web content + database ?
