Does Exchange Server Cumulative Update auto-backup web.config files?

Occasional Contributor

Hello all,


Exchange Server Cumulative Update newbie here.

I take heed of the following advice from https://learn.microsoft.com/en-us/exchange/plan-and-deploy/install-cumulative-updates?view=exchserve...

I have noticed that it appeared during Exchange Server Cumulative Updates, the following web.config files are automatically copied to web.config.bak before web.config is overridden. (example is Exchange 2016)

Can someone please confirm that for me?
