Yep, finally did it.
Started the migration of my personal server.
Broke a lot of stuff, fixed even more, and there is more work to do.
I’m really surprised how fast is PHP 7,
and how HTTP2 module on Nginx 1.10.0 makes a lot od difference.
I also moved from 64-bit to 32-bits. Doubt that I’ll ever use 4+ gigs of RAM on my DigitalOcean instance.
There is one thing still bothering me. On old server sendmail works, on new one I wasn’t able to make it work. Google just ‘ignores’ my mail.
I’ll probably try with another MTA.
