SQL 2008 authentication: safe to change from Windows to mixed mode ?

I have been asked to use an existing SQL 2008 server for a new database for a new client-server app. Currently, SQL authentication on this SQL server is Windows and it is being used for a production line-of-business app. However, the new app requires mixed mode authentication. I know how to change from Windows to mixed authentication. However, is it safe to do this? Are there likely to be any implications for the original app?

there is no implications for the original app.
the implication is only security for the database, as all the non-windows logins will be able to be used.
you may consider installing a dedicated instance for this app, if it's a small one ...

Is it possible to create an sa-type SQL login which only has superuser rights on the new database? Would this be easier than giving the implementation team for the new app the sa credentials?

logins with sa power (sysadmin server role) have permissions on all databases.
you can create a normal login with no special server roles and make it db_owner (full power) on that database, the login will not be able to do anything on the other databases.

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Re normal login with no special server roles, making it db_owner - OK.

Re "all the non-windows logins will be able to be used" - if the new app implementation team had neither the sa credentials nor a Windows account with admin rights over SQL, would this be an issue?
