Migrating vCenter with VBA

Hi Community,

We actually are running our VMware Backup with EBR 1.0.3.6 and Networker 8.1.3.2 in a vSphere 5.1 environment (windows 2008 R2)

We need to change the vCenter for a new one (other name and IP) mounted in version 5.5 on a Windows 2012 R2

How can we at best migrate our VBA. I think we need to build new one, but in that case, how can we keep the history of backup done in the 5.1 environment? Is it possible to restore a check point from one VBA to another one who run in another vCenter?

Thanks.

Greg
