You can have a ‘master’ site in pre 5.6.
We have been multi-site here for versions 3.5 through 5.4 and set up our own ‘master’ site.
I is really fairly simple and our transition to the Cloverelaf supported madster site went quite smoothly.
You do a site init to create a site. This site will NEVER have a NetConfig nor will it ever be started. It is simply a directory structure to be a repository for your common objects (Tables, variants, procs, etc.).
Then you do symbolic links from your various sites to the ‘master’.
With Cloverleaf 5.6 and beyond the need for symbolic links goes away but now all your common objects are where they belong because when you get to 5.6 or beyond you simply make your ‘master’ site the Cloverleaf Master Site.
However, transitioning from a single site environment to a mulitple site environment should be undertaken after some thoughtful planning not just firing up new sites.
There are upsides and downsides to multiple site environments but overall I think multi-site is worth it.
I mainatain it is not whether you will be multi-site but when.
I have operated in a multi-site Cloverleaf environment for nearly 15 years. First with my former employer where we were either the first or among the first multi-site environments, through my current employer weher I brought in the concept.
