Bonjour Ludovic,
We do not allow the creation of remote depot for performance reasons. We are aware that some licensees are replicating our streams using P4 transfer: GitHub - perforce/p4transfer: [Community Supported] Utility for transferring a subset of files (with complete history of all changelists) from one Helix Core repository to another, only requiring read access to the source repository.
We are aware that the script tries to replicate the full streams which results in hitting the maxscanrow limit. You will have to modify the script so you can restrict the replication to a smaller subset of the streams.
Regards,
Martin
