I know that JMS works by sharing php files (db and install files). By doing this, it is able to create various sites based on the same files and joomla version of course. This means that all sites will have the same joomla version.

My question is: is it possible to setup websites with different joomla versions with JMS?

The reason I want to do this is that I work for a hosting company. Sometimes, customers sometimes develop their sites in different joomla versions. My job is to import those sites into my hosting servers. What if the customer uses joomla 2.5 or 1.7 while the version JMS is installed on is 1.5. This will cause conflict. I just want to know any work arounds.

I have figured that a possible work around is to install the different joomla versions and install JMS on each one of them. That way I would be able to host different joomla versions. But what i'm looking for is to avoid that. I want to host different joomla versions from just a single joomla install which will serve as a master.

any suggestions are very much appreciated. thanks.

You have perfectly understood that the concept of JMS is to share the same joomla application and that you can not have several joomla version into the same directory.

So today, you have to install several joomla version with a master.

The only thing that is technically possible is to share the slave sites definition between the different joomla version. So that each JMS master will manage the same list of sites. This is not recommended because this is the master website that is runing that will decided of the directory structure. This can be inconsistent with the DB content to replicate.

So we don't have work arround to avoid installing several joomla version.

Thanks for the support. I guess I will test it first. Otherwise, I will have to install the versions separately.
