We have a MICS rls1-t1 also our fiber Nam is at 3.0.10B We want to upgrade the MICS to 5.0 will we have to upgrade the VM also? Or will it be ok? I was told to beware of some Nam 4.xx problems? Is there some patches also needed if a upgrade is necessary? I'm not familiar with patches how do they work? Do u purchase them along with the upgrade? Could someone assist me in the steps to upgrade VM frm 3.0 to the next higher version that is compatible with MICS 5.0.
