We trying to upgrade the CUCM 8.6.2a restricted version from 6.1.5 SU3 . We gone through the readme document of Refresh cop file 1.1.
*** If upgrading from a 6.1(4) or 6.1(5) or 7.1(3) version to an 8.6(x) UNRESTRICTED version, only this patch is required. It is NOT necessary to also install the ciscocm.allow_upgrades_to_unrestricted.cop.sgn patch.***
As per above message we no need to install the COP file if we go for 8.6.2 restricted version !
Is any one came across this kind scenario's ? Looking for your feedback & suggestions.
Thanks in Advance
