I don't have many issues... but when I do it is usually a bad one.
I took my CRM 2013 install running on Server 2008 and did an upgrade to server 2012 R2. No issues. All updates applied. From there I run the CRM 2015 installer to run the upgrade..... Yes, running as admin, and after the "Pre Flight Check" everything is good. From there the install starts to copy files..... I get this error.
00:16:43| Info| CrmAction execution time; BackupUpgradeDataAction; 00:00:03.0020974
00:16:43| Error| System.Exception: Action Microsoft.Crm.Setup.Server.BackupUpgradeDataAction failed. ---> System.IO.FileNotFoundException: Could not find file 'C:\inetpub\wwwroot\web.config'.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

I am finding no references to this issue any where. Looking for suggestions. It appears that this file does not actually exist. Somewhere during the upgrade maybe it got deleted. I have put an old web.config file in this path, rebooted everything and still get the same error.
Looking for some suggestions.
