Migrating Backups from StoreOnce to another Repository

[mix]

Dear Community,

I have an old StoreOnce Catalyst from which the backups in Veeam are shown as Disk (imported). The backup jobs no longer exist. I need now to move all the historical backups to another repository, ideally an S3 Bucket (or even better Glacier) for long term archival.
The StoreOnce is a single Repository, was not part of a SOBR. My first idea was to add it to a SOBR as performance tier and use the S3 bucket as capacity tier, but because the backups do not have the GFS flags i guess that the data will never moved to the capacity tier. Also copying the backups to S3 and rescanning the repo I think will not work because S3 is an object store and Veeam handles the files in a different way.
What is the best way to achieve this? Maybe someone has some experience to share?

Thanks & best regards!

Hello,

but because the backups do not have the GFS flags i guess that the data will never moved to the capacity tier.

did you try it out? Because GFS flags are only needed for archive tier. capacity tier works without GFS.
