# Merge changes across streams

The Dimensions CM for Eclipse integration enables you to merge changes in streams. You can view differences, apply changes, resolve conflicts, and then deliver the changes to a target stream in a repository.

For an overview of merge guidelines and behaviors, see Merge changes.

In this topic:

## Cherrypick changes to be merged

When you merge changes between streams, you can select changes related to specific requests, known as cherrypicking.

For example, you have delivered multiple sets of changes to a stream but want to merge one specific set into a different stream.

For details about cherrypicking changes, see Merge specific changes between streams.
