target is to upgrade sharepoint 2013 to 2016. i have backed up the contentDB and restore it it will mount in new web app in 2016 farm but there s some problem: first. it kinda seem like it mounted uncomplete because when i view my site collections in central admin at left i can see my site collection but at right there s no box of information. second. after mount i run upgrade-spcontentdatabase command but i got error about RBS.(it seems farm 2013 database was RBS enabled but in new database i failed to enable rbs) i tried to disable rbs from content database by run commands in this link https://docs.microsoft.com/en-us/sharepoint/administration/disable-rbs-on-a-content-database but nothing happend how can i disable RBS ?
I would recommend creating a new contentDB in 2013, without RBS enabled on the DB. Then use powershell to move the site in question to the new database, Move-SPsite command. Then migrate the new clean DB to SP2016.
I also found this article, but I don't think that the BLOBS are actually moved from the file system back to the content DB, so proceed with caution. https://docs.microsoft.com/en-us/sharepoint/administration/disable-rbs-on-a-content-database
