Downgrading a
Single-Site System
(7.1 to 7.0)
VCX S S
ERVER OFTWARE
The VCX system supports two operating system images. If the
■
upgrade required installation of a new VCX operating system version,
then the downgrade must revert to the previous installation.
The person performing the downgrade should be trained in VCX
■
operation and procedures, and be familiar with VCX terminology.
This downgrade procedure assumes the VCX version 7.0 system
■
databases were backed up before the upgrade to version 7.1 was
performed. These version 7.0 backups will be restored as part of the
downgrade procedure.
Note that the downgrade procedure does not remove VCX version 7.1
software from your VCX system.
This procedure describes how to downgrade a pair of VCX servers
running these software configurations:
IP Telephony and Messaging
■
IP Telephony only

IP Messaging only
