We were able to virtualize our server, which means we now have access to a newer version of PHP, which means ... I can upgrade the POYi Archive from .90 to the current version. I've seen the instructions on Omeka and I'll upgrade a development version first to make sure I don't hit any snags or am able to work out any snags before I upgrade the main site. I'll also document the upgrade process. If there's anything anyone knows ahead of time, tips, etc., I'm all ears!
