You use the Content Compare and Import tool to compare and import content differences from one CQ instance to another CQ instance. It's only necessary to install the bundle containing Content Compare and Import in the CQ instance where you use the tool.
You can access the Content Compare and Import tool directly in a web browser at the following URL: http://<host>:<port>/system/console/contentPull
The instance that is being accessed is the "local instance." The instance that is it is being compared with is the "remote instance." When you access the tool, you are presented with the screen below.
For the tool to function properly, it's necessary to install it on the "local instance" only.
When running the tool, make sure to use the admin account for doing the comparisons to prevent permissions issues.
When doing a content comparison, the result only shows differences between the two CQ instances. It does not show nodes or properties that are matching.
The result of a comparison shows the following types of differences:
Scenario 1 - Comparing Content: Here is an example of running a comparison between two running CQ instances for the path "/content/geometrixx/en/toolbar."
When doing a content import, the tool displays the differences along with a description of the changes that were made to bring the two instances in sync.
The result of an import can be interpreted as follows:
Scenario 2 - Importing Content: Here is an example of running a content import from a remote CQ instance to a local CQ instance.
If a property does not exist on the remote instance, then the tool doesn't remove the corresponding property on the local instance.
