For the majority of my time in my current position we've done all of our FileMaker upgrades as "in-place" upgrades, e.g. uninstall old FileMaker, install new FileMaker - all on the same server.
Due to the impending EOL for Windows Server 2008 R2 we are provisioning new Virtual Machines instead of doing "in-place" upgrades.
I've done some searching on the forums and have found some discussion about migrations, but they are very high level - "copy the databases from old server to new server".
What I'm curious to know is if there are any best practices for doing the copying and/or how you have handled this in the past.
I know that rule #1 is to make sure the files are closed, but beyond that ?
Mount a network drive and just copy and paste?
Our largest set of files is about 150GB of databases and external storage.
We do have a set of test servers, so I was planning on doing a test run.
