mode to B2BUA mode
After upgrading the OCS/Lync gateway VCS (cluster) to X7.0, the following procedure should be used
to migrate from use of OCS Relay, neighbor zones and CPL to using the B2BUA and registered

FindMe users.
On VCS:
1. Back up the VCS configuration:
Maintenance > Backup and restore > Create system backup
file
. If using a VCS cluster, this has to be done on all cluster peers.
2. Go to
VCS configuration > Dial plan > Search rules
and delete all search rules targeting the
neighbor zone(s) towards OCS/Lync.
3. Go to
VCS configuration > Zones
and delete all neighbor zones pointed towards OCS/Lync
peers
4. If previously using OCS Relay:
a. Go to
VCS configuration > Call Policy > Configuration
and click Delete uploaded file. If
using a VCS cluster, this has to be done on all cluster peers. Please note that if the OCS
