[EP-tech] Re: Upgrade processes for EPrints

My suggestion is to just make a backup of the code, do an upgrade and make a diff, to find the changes. Evaluate if some of them can be done using triggers, so no more code changing in Eprints.
If you use some virtualization, you can do it in a cloned machine (with just a different ip and a different virtual domain - a new dns entries) and when done, just change the domain in Apache to the production and the ips and do an apache reload.

Hi all,
I’m planning an upgrade to live EPrints, which will likely involve some downtime as it’s the first time I’ve done an upgrade on the live system. It’s not going to be a big leap in itself (3.3.13 -> 15), but I’ve made a lot of customisations so it’s a little nervewracking.
Does anybody have any maintenance processes they can share? I have some ideas about how to approach this – I’m interested in things like how much notice to give users and the best method for doing that, how best to make the site generally unavailable, what should be backed up, how you test a successful upgrade and so on. I’d be grateful for any advice / suggestions / cautionary tales and apologies if I’ve missed a very obvious wiki page!
