About merging in UCM
A merge combines the contents of two or more versions into a single new version. During a deliver or rebase operation, the DevOps Code ClearCase® merge algorithm involves the following versions:
- The source contributors: one version from your development stream and one version from the target stream.
- The base contributor: the common ancestor of the source versions.
- The destination version: the merge output, which in a deliver operation becomes a new version in the target stream and in a rebase operation becomes a new version in the development stream.
