About

Three-way merge allows concurrent development. ¹⁾

It involves three files:

1. The (Original|Received|Master|Parent) files: the original local file before modification.
2. The Target/Modified File: the local file with your modifications.
3. The Current/Production File: Generally, the file that is in production and where some modifications may have been performed by other people.

Steps

The merge process involves three steps :

• Comparison between the current and the target file to find out your modifications
• Conflict Resolution or Reconciliation (if any). You must decide which modifications are applied.
• Merge. The last step is where you just start the merge action.
