Upgrading from 3.4.5

I’m currently using RT 3.4.5. I’d like to upgrade it. I was
wondering if I should just go straight to 4.0.x or go to 3.6, then
3.8, and then to 4.0. What would you suggest?

Thanks,
Jaime

Going straight to 4.0.x is fine. There are a number of important
database upgrade steps you need to do, so read all of the README and
docs/UPGRADING-3.4, docs/UPGRADING-3.6, docs/UPGRADING-3.8,
docs/UPGRADING-4.0 and docs/UPGRADING.mysql if it applies to you.

Thanks! As it happens, I did notice those files. I went looking for
“readmes” before bothering the list. :slight_smile: Reading the files made me
wonder if I should do this incrementally, though.

Thanks, Thomas, for the quick and thorough answer. This is going to
save me a lot of time.

No problem. Glad to hear you’re upgrading. :slight_smile: You may also be

Thanks. I was assuming I should “mysqldump > backup.sql” just to be
safe. I don’t run it in a VM (I’ve used RT since before VMs were
fashionable), though.

Any thoughts on the mysqldump idea?

Yep, all of our documentation tells you to take backups. For backing up
a 3.4.5 database, you’ll want to use the --default-character-set=binary
option. See also UPGRADING.mysql.
