We have a custom sharepoint solution which we are deploying in standalone environment. Now we have to deploy on farm environment where we are going to create multiple web application and hosting our different version of the product on different site collection of web applications.
I will manage 14 hive folder for css and jquery by maintaining client related folder. I will rensam the solution and change the solution id for each client.
The problem is, when I try to deploy a solution on particular site, it is throwing an error by saying 'feature is already installed.' How to manage the same feature for different clients?
