This case is another one of those countless issues which reminds you every day that no matter how long you have been doing migrations you can never rest on an old knowledge and experience. Rather you need to keep learning something new which may at first appear same old, that’s a nature of our job 🙂
“WMI Provider Error: Cannot find object or property” during SQL Server migration

You may run into an error “WMI Provider Error: Cannot find object or property” during SQL Server migration, in particular when switching SQL Service account from Source to Target. The error occurs because SQL is normally encrypting client-server communications via SSL and needs certificate for that purpose, so it’s trying to obtain […]

Obtaining a quick report in MS Exchange about DLs activity
Just wanted to share a quick PowerShell one-liner which outputs a report of how many messages were sent to DLs during particular period of time.

How to configure Ex 2013 Throttling for Migration
Recently I came across a very good example where Ex 2013 throttling issues were interfering with the mailbox migration so wanted to share here. Partially it was due to MAgE agents not caching Autodiscover requests properly (QMM 8.11 fix is coming out soon around spring 2015, 8.10 is already patched). So what was happening, 40 agents were running with […]
Don’t forget to disable CRA (Calendar Repair Assistant) before the mailbox migration
If you are in the Calendar sync coexistence scenario during migration into Exchange 2010/2013, CRA (Calendar Repair Assistant) can cause a lot of troubles in terms of duplicate Calendar items.
