Jep, that's exactly what I did. I previously used an external USB-HDD-cage to house the storage pool (Win10 Storage Spaces with parity), but changed this setup to the data having an own server, but using the same HDDs, this time placed internally, forming the new storage pool (same(ish) setup, with the same data).
Since I had not enough money to buy new HDDs, I "unsynched" the old pool, exited odrive, copied the folder structure (5mb in size) to a temp location, built the new server, mounted the new storage space (with the same letter) on the "original" server and copied the structure over and started odrive again. I then chose "download everything" in the dialog of the "sync" command of the top most folder, which prompted the re-download of the entire data within the structure, thus saving me the PITA of copying the stuff over HDD by HDD or having to buy new HDDs. The 17 terabytes should be in place again within the next two days.
