Silverstripe Version:3.7 to 4.5

Question:dev/build creating new tables but no data being migrated

Hi there,

i am in the process of upgrading Silverstripe site from 3.7 to 4.5. I am following the steps mentioned in the upgrade doc. In the step where it says run dev/build…i did it. New tables are getting created with Namespaced table names ( I have not added private static $table_name yet)…that’s fine with me…unfortunately the data is not getting migrated to the new tables. I cant seem to understand why, the document says it should. Can someone please let me know what i might be missing?

Thanks
DR

Another approach is to just manually rename your old tables in the database to their namespaced equivalent.
