Migrations

So, our infrastructure and communications teams just took us through a migration of our email system.

They did a fine job, but there were some bumps in the road. Most of the time, when you migrate email servers, it’s not too big of a deal; you’re in control of the machines, and you’re going to have fallovers and failsafes, etc.

However, note that from a user’s perspective, changing MX records and the intricacies of the DNS system are deep fu. So just try to make those changes on Sunday at 1 a.m. Trust me, it’s best that this is happening while everyone is sleeping, because the fewer conversations you have to have about DNS propagation & replication, the happier you will be.

There are other lessons that we learned, but that is the most important one.
