using team foundation power tools tfpt “an item with the same key has already been added”

Question

We are using TFS 2012 I downloaded the TFS Power Tools for vs.net 2013 I am running on windows 7 64bit

I have changed directory into the source branch. Executed the following

tfpt unshelve shelfsetname /migrate /source:$/path1/v1 /target:$/path1/v2

I continually get error An item with the same key has already been added

I have tried many options, including checking out the shelfset, shelving the set again while not keeping any local changes etc.

I have removed cache files from paths C:\\Users{user}\\AppData\\Local\\Microsoft\\Team Foundation\\4.0\\Cache and C:\\Users{user}\\AppData\\Local\\Microsoft\\Team Foundation\\5.0\\Cache

Any ideas i am at wits end.

I have found other stackoverflow posts like here and tried those options too

Answer 1

You should undo all other pending changes from the root of the branches. Then only you would be able to migrate the shelveset.
