BVBHosting

I recently received a client who has a WHMCS through which manages its host and vps, the WHMCS was implemented after the cPanel was operating with some customers so my first question would be to consolidate old customers (plans, services , expiration dates) along with those created after the implementation of WHMCS. On the other hand also have VPS Proxmox sold through before implementation and I would like to consolidate this information. Note this desface because recently the migration of a Proxmox server from France to Canada and continues WHMCS linking the Proxmox server France, trying elimitar was held this link tells me there are services associated with this server, also wanted to finish WHMCS decouple servers use either.
