Joshua,
Higher Education Library Technology (HELibTech) lists who (UK HE institutions) has what library system and the 'Procurement' page http://helibtech.com/Procurements lists changes over the last 2+ years. There are some innovative customers in Wales who moved to Alma. I'm sure people at those institutions would be happy to help..

Subject: [CODE4LIB] Experience migrating to Alma or OCLC WMS?

We are exploring migrating from a III Sierra system to Alma or OCLC WMS.
Does anyone have any experience with a similar migration you'd be willing
to share?
