Over the years I've collated various 'frequently asked questions' (and responses) about MQ clusters into a series of blog articles - not so much reference material or 'how to use', as background on why some features of clusters work the way they do, and best practices you can employ based on that knowledge.

Unfortunately, when we migrated a lot of our blog content to the Community platform, some of these became a little hard to find (if you are looking for old blog entries generally, you'll find them in the library section of this Community group. )

As I've had a few queries about where the 'Cluster FAQ' series have gone since the migration, I thought it was worth reposting direct links in one place to make these easier to find again in future:

Why only two full repositories?
Relocating Full Repositories
How big can a cluster be?
Managing mixed versions and upgrades in a cluster
Montoring the cluster repository process

Nothing new here I'm afraid, but hope people find this useful - and note that there are several other excellent articles on Clustering from other authors, both in the archive linked above and elsewhere on the Community site, so please don't treat this list as exhaustive!
