[Koha] Upgrading from Koha 17.11 to 18.11 --- anything to watch out for?

[Chris Brown]

Hi Hector,

Thank you for your advice -- I will keep it in mind. We plan to upgrade
over Easter when the libraries that we support will all be closed. I will
take a full snapshot of the server (virtual machine) first so we can roll
back if disaster strikes, and we already keep off-machine daily backups.

Do I still need to apply the "auto increment fix" in 18.11?
