Andy Levy has a problem. Well, about 8000 of them. In part 1, he describes the plan:
How do you move eight thousand databases in a reasonable amount of time? I spent about an hour and a half one morning hashing ideas out w/ folks in the dbatools Slack channel, plus several conversations in the office and with our hosting provider.
Then, in part 2, he describes the execution:
We missed the estimated time for our go/no-go decision by five minutes. With the number of moving parts, databases in play, unexpected delays, and amount of testing we had to do, that’s pretty good! My colleague and I had some additional work we needed to take care of after the team declared the migration a success. Agent jobs needed to be enabled, overnight job startups monitored, things like that. We called it a day after about 14 hours in the office.
It was a nice success story, so check it out.
