I am attempting to install 2.5.1 over 2.1 in order to get to 2.6. Unfortunately, the 2.5.1 update installer fails every time saying pre-requisites aren't met. The log doesn't tell me anything more than the exact same failure message. OS is compliant with the requirements. What else could it be looking at and causing it to refuse to install? I downloaded the 2.5.1 update/upgrade package from Cisco.
thanks for your help
Anything with with a major.minor version that matches what you have now is safe. That is, CS 3.0.6, RME 4.0.6, CM 4.0.10, DFM 2.0.10. Everything else is part of LMS 3.0.
