So we have created Sharepoint 2013 Webparts for a Specific solution. As we didn`t have TFS and had multiple developers work within one install on a remote server , we separated into multiple projects currently 107 + all talking to the same database via a Data Access layer. Thus we have multiple wsp files that we retract and deploy against our Sharepoint site.As it seems a big tasks to collapse this into 1 wsp file , we would like to get a feel if it would be worth the effort ?

WHich one is better and why ?

If a single WSP file solution is best , how would a person go about updating all the name spaces ect in all the 107 projects that live in the solution ?

Thank you for your assistance
