Get-SPServer shows that all servers in the farm except itself need to be upgraded. Is there a problem?

Question

This morning I was reviewing the SharePoint Health Analyzer alerts and came across an error that one of my non content databases (Search) was "in compatibility range and upgrade is recommended." I went ahead and ran psconfigui on one of my application servers which completed successfully. Afterwards, I re-analyzed the warning, and everything cleared up. One interesting thing I am noticing, however, is that when I run the Get-SPServer | Where-Object {$_.NeedsUpgrade -eq $TRUE} command, each server in the farm will return False for itself and show that all other servers are True. Even the server that I ran psconfigui on will appear as needing an update according to any server in the farm that isn't itself. Is this a problem? What can I do to resolve this issue?

Answer 1

if you are behind the from the Microsoft CU then server will complain about the upgrade required. I.e you are Jan 2015 CU but MSFT release the Nov CU, in this case you are behind couple of cu.

It will not be a problem but i would install the latest CU and run config wizard if i am way behind.
