Multi-tiered, transactional reverse deployments

System

I have one Open Deploy 5.6 Base server. I have 2 web farms: Test and Production. Prior to deploying to Production, I need to back up Production to an area on the Base server using a reverse deployment. Because Test is not a base, I also need to do a reverse deployment of Test to a staging area on the Base server to prepare for Production deployment. Both of these reverse deployments may happen at the same time, but both must be complete before I deploy from the staging area on the Base server to Production.

So, in a nutshell, I have to do 2 reverse deployments transactionally, then invoke transactionally a forward deployment to one of the farms that was one of the reverseSources. The idea is that if any of the 3 steps fail, all roll back.

Here are my issues:

- How does one specify a multi-tiered deployment on a reverse deployment? Because the reverseTarget is localnode, there's no noderef element to contain the invokeOnSuccess attribute.

- If the above answer is to put the attribute on the noderef for the replication farm used as the reverseSource, can I get it to only invoke when Production is the reverseSource and not when it's the target?
