In multistore - installed extensions and upgrading

[llegrand]

When one has a multistore setup  I have some ongoing maintenance and extensions questions. 


What happens when you have extensions installed? 

In particular,  extensions that have fees?  Do we need to purchase an extension for every store?  or is it inherited during setup?  If additional purchase - what about multiple license fees at reduced cost?

When there is a version upgrade,  and it is run on the master - is it also necessary to run it on each of the store in some manner or are the features  shared from the master upgrade?

These are important operational issues for deciding how to manage sites after setup.

Thank you for your answers.

I believe, extensions licensed per AbanteCart installation. This is not limited to number of stores with in each AbanteCart installation.

I am not sure I understand your answer correctly.

Are you saying that a master store with 10 mutli-store setups is considered to be one installation.  And that an extension is good for all 11?

Or are you saying it is considered to be 11 installations?

Yes. One AbanteCart installation is  =  1 code instance = 1 license

If you use one AbanteCart with multiple virtual stores configured it is still 1 code instance.
