How to Perform a Baseless Merge

- J.D. Meier, Jason Taylor, Alex Mackman, Prashant Bansode

To perform a baseless merge, you use the tf merge /baseless command from the Visual Studio 2005 Command Prompt.

For example, the following command line will perform a baseless merge from the source branch to the target branch. The /recursive switch is used to perform a recursive merge of all the files and folders within the specified branch path:

tf merge /baseless <<source path>> <<target path>> /recursive

 tf merge /baseless c:\data\proj1 c:\data proj2 /recursive

The process of merging items that are not directly branched from each other is known as a baseless merge. For example, you might want to merge a change between two release branches that are siblings of each other without merging up to the parent branch. Baseless merging only works from the command line; you cannot perform a baseless merge from Visual Studio.

When you perform a baseless merge, TFS does not have any information about the relationship between the files in the branches. For instance, a file rename will be viewed as a deleted file and a new file in the branch. For this reason you will have to perform more manual conflict resolution than you would when performing a normal merge. However, you only have to perform this conflict resolution one time. After you have performed the baseless merge, TFS records history and establishes a relationship between the folders/files.

Baseless merges can only be created from the command line. Even after the first baseless merge, when a relationship has been created between the branches, future merges still need to be created from the command line.
