I'm hoping this is a relatively simple question.
I have a CUCM server version 6.1.2.1139-3. I need to upgrade this to 6.1(5)SU3. When I start hopping around the software compatibility matrix looking for my upgrade path I do not see 6.1.2.1139-3 anywhere in the matrix so I'm having trouble figuring out the upgrade path. I don't think I can go directly to 6.1(5)SU3 because no versio nof 6.1(2) can do that. But what intermediary version can I go to?
Regards,
Steven
