Can you setup DRDB later?

Hi guys

I am coming up on a deadline to migrate to a new facility in another city, already have a proxmox server I am planning to recycle and move to the new facility. However, in the interest of avoiding downtime I am planning to build one new proxmox box at the new location and set it up in such a way that I can later on (a week or so) after all my VMs are migrated to this new box, to use DRDB without downtime.

Is it possible to use DRDB on a single server, then "enable" duplication to the slave box? Theoretically, I am thinking that overnight I can have the boxes sync/migrate data so they are up to date on both servers. Any guides or tips as far as doing this, most importantly can I pull it off?

Thanks

Hi,
you can also use an pre-copy for sync like discribed here:
