Thanks kautuk.
Im using higher version of crx2oak as 6.1 to 6.3 was successful.
As part of our deployment model for every deployment , im trying to spin up a fresh instance and migrate known content paths from old repo.
The way im running now for a repository with file store is by explicitly mentioning paths src-datastore and target datastore. Is it not the right way ? When you mentioned FS copy , did you mean simply copying the directory like via rsync to target directory or running crx2oak with some different input params ?
Thanks
