Make recovery images of servers
After you have upgraded software as
instructed in these procedures and verified that your system
is working properly, you should always make a recovery image
of each of your upgraded computers. Use a sequence of tasks similar to
those you followed for upgrading software so that as you take systems
offline you manage redundancy, servers, and clients, as appropriate
for your system.
Refer to the Grass Valley product's Service Manual for recovery image procedures.
