I changed to a new PC and am trying to move my hydrus database/files to the new computer from backup. I want the contents of the database on a secondary drive while the program is on my main drive. I followed the help page to migrate the database location to my secondary drive (https://hydrusnetwork.github.io/hydrus/database_migration.html#intro). But, now I can't import my backup because it says my "database is stored in multiple locations." But there's only 1 location in "migrate database" window - the new location on my secondary drive that I specified. How can I import my backup to the database?
