Thanks for your info!
I just updated the gist, considering:

• #973 Use config in flushing cache in migration file
• #1146 define index name

I didn't test the changes yet.

@fabricecw Shouldn't all the insert statements also use the $tableNames array instead of hard-coded strings?
For example (line 91):

DB::table($tableNames['roles'])->insert($roles);

instead of:

DB::table('roles')->insert($roles);

@Yoeriwalstra correct. I just changed the static table names to the config values. If you're able to test it, let me know if it works. Thanks!

Worked perfectly for me, amazing work.

Thanks a lot! It is useful in 2024. Good job
