I have an on-prem (2013) site with 200+ subsites all created from the same template with the same document library just because users wanted to re-use the same filenames (and document library names) for different suppliers.
So 1 site for each supplier with a portal site with hyperlinks to the subsites on top.
Since we decided to phase out our on-prem environment this site will have to be migrated to SPO.
Is it wise to move this behemoth of sites to O365 just as is? Or is their a better restructured alternative I'm missing? I'm curious about the experts experience on this or if others have experienced a similar migration.
