Hi,
after upgrade you have to Reconfigure pairing between sites or repair connection from one site to another. This should be one time effort and it's needed to renew the certificates information in SRM after all upgraded products.
You can find more useful information in our documentation - Site Recovery Manager 6.1 Documentation Center
Procedure
1
| In the vSphere Web Client client, select , right-click a site and select Reconfigure Pairing to reconfigure the connection between the Site Recovery Manager sites. |
Hope that this help,
Daniel G.
