Hi, I did add the following line in my db context OnModelCreating method
modelBuilder.ChangeAbpTablePrefix<Tenant, Role, User>("");
and added a new migration.
Then ran the migrator project to update the db, but getting the following error message and it happens on a newly installed system with no additional entities.
am i supposed to do something else?
thanks

Hi @uenlkr4e
If this is a clean system (no existing data):
- Simply delete the database and run the migration again using the migrator or
update-database. - EF will recreate all tables from scratch, including IDENTITY columns, without any issue.
If you already have data or want to preserve the database:
- Open the generated migration file and manually remove the part that tries to alter the IDENTITY column.
- Alternatively, instead of renaming via migration, consider using raw SQL (
sp_rename) if your goal is just to rename the tables.
