Rolling back files moved during migration of Elvis 4 to Elvis 6

Rolling back files moved during migration of Elvis 4 to Elvis 6

If the migration of content from Elvis 4 to Elvis 6 failed for some reason, you can roll back any Elvis 4 files that have moved to Elvis 6.

This article explains how this is done.

Step 1. Run the Migration tool by entering the following in the command line:

  • For Mac OS and Linux:  sudo java -jar elvis-migration-tool-x.x.x.jar
  • For Windows: java -jar c:\elvis-migration-tool-x.x.x.jar

Note: The default port for the tool is 8080. To change the port, use the 'server.port' command line option:

  • For Mac OS X and Linux: sudo java -jar elvis-migration-tool-x.x.x.jar --server.port=8181
  • For Windows: java -jar c:\elvis-migration-tool-x.x.x.jar --server.port=8181

Step 2. Access the Migration tool by entering the following URL in a Web browser:

http://localhost:8080/

Note: Make sure that the port number corresponds to the one that was specified in your command line.

Step 5. Access the Rollback tab and enter the following details:

  • Elvis 6 Folder. The location of your Elvis 6 config/data folder.

Note: This field is pre-filled with the location of a default Elvis 6 installation, based on the operating system.

  • Dump name The name of the dump which is to be rolled-back.

Note: This field is pre-filled with the name of the last dump.

  • Move files. Select this option when you are going to move files back from the Elvis 6 storage to the Elvis 4 storage instead of copying them.

Note: Moving files is quicker than copying them.

Step 6. Click Start rollback.

Progress bars appear to indicate the progress of various steps of the process.
