Yes, of course!
I understand you want to move your servers from one account to another one, right? To be able to recover the server easily, create a backup of the instance before doing anything.
Then, to move the server to a different account, you can follow any of these paths
- you can share that backup with the new account and deploy it later.
- Launch a new instance and migrate the data from the old server to the new one by following this guide (however the plugin is not free for multisite)
- or you can copy the entire installation folder and move it to a new instance
If you follow the first approach, you won't need to do anything more apart from configuring the domain with the new IP address. If you go with the other approaches, you will need to configure the SSL certificate in the new instance.
You can also contact the Google's support team to know if there is any way to assign the current server to a new account so you do not need to follow these steps to move the server from one account to the other
