SCCM Servers not Patched
Recently I got into a project to do the upgradation from 1810 to 1910. Before I could start I noticed that these SCCM physical servers (1 CAS, 2 Primary) has not been patched from one year.
Most of the SCCM Servers are 2012 wintel team have decided to go for server OS upgradation to 2016 / 2019.
When I checked with out patching team to include these servers into their patching cycle they bluntly said its running on very old h/w IBM x3650 and this potentially cause server crash hand SCCM might breakdown
Whats the best solution?
Can i upgrade sccm without its servers having recent patches?
