Hi,

Let's say 3 development teams (1 at customer's site, and 2 consultants) with no LAN or VPN to join them, only mail or ftp. Each team owns licences for SF and DDT, and can create deployment packages to apply on customer's SQL Servers (and of course on SQL Servers for tests at consultant's office)

When I receive customer's package, I can import it in a profile and deploy it from that profile. From another profile, I generate a package, and customer may deploy this package I'll send him. And of course, each deployment delete and  replace what was locally written

How could I merge the 2 packages into a single, in order to see all modifications in a single profile? from within DDT? with a merge replication in SQL Server? with a versionning product (Visual SourceSafe or another one)?

Thanks in advance for all advice.

Well, based on that description, with all of you working on the same app just in different stages, I'd actually recommend getting VPNs set up to one central location, and managing it all on the same profile on the same server. That's what we do with remote teams, and it works well for us. That way there isn't any need to pass DDT profiles back and forth or do anything fancy to keep everything in line.

You just have to communicate with each other regarding what you are working on so you don't step on toes, but doing the above will keep you from losing work in the shuffle.
