Is it possible to roll back Metadata Changes made on Documents?
This is possible, but not practical. It requires us manually checking the old log files for the metadata that used to be associated with the document and then providing this to you to apply in batches or per document level on the platform.
This is time consuming and should only be done as a last resort, as in the instance of say, 80 documents being written over, this could be days of work to recover.
The best practice is to always export a CSV of the workspace if you are going to be making any large bulk changes across bundles - as this will give you a backup to fall back on if the situation calls for it.
