+### Update release-branch `.target` files
+
+Next, we want to change the `.tpd` and `.target` files to point to the correct P2 repository locations in the release-branch. This happens by opening the previously edited `.tpd` files in Obeo's editor and regenerating the `.target` files by pressing Alt+R.
+
+Push the changed files to remote again with commit message:
+
+ Configured release/x.y.z[.w] branch .target files.

+### Test Release Train build
+
+Trigger an execution of the [simantics-release-train](https://www.simantics.org/jenkins/job/simantics-release-train/) Jenkins job with parameters
+* GERRIT_REFNAME: `release/x.y.z[.w]`\r
+* PUBLISH_ARTIFACTS: `true`\r
+
+to ensure that all components of the release train build fine and to publish first versions of P2 repositories of everything online.
