Actually there are more issues with mssql migration.

After I changed the client name to mssql, I could run that script, but more errors when I run:
npm run migrate

1. failed to parse server name when I put localhost\SQLEXPRESS, then
2. failed to parseInt of port

After I manually hard coded it, it failed to login with my 'sa' account...

Please test again before release it

It will need the connection string that is being generated:

mssql://root:password@localhost:1433/${name}
