Slowly moving all my webservices from one server to another because years ago I made the mistake that I didn't use LVM and now I'm constantly battling with having too little space on my root directory. Because of that at least once a week some or several of my services go down.

I probably could fix it somehow, but moving things between servers is also an interesting exercise in if you still understand what you set up several years ago. Especially because I'm doing it manually, without ansible or similar tools.
