ACS Migration 4.2 to 5.6 using CSV import

[mattsmithspad@hotmail.com]

Hi

I am looking into different ways of migrating an old instance of ACS (v4.20) to our current ACS server (v5.6.0.22)

As it stands, both ACS servers are in production and need to find a way to migrate users, groups and network objects to the newer instance. There is some risk that users will be configured on both servers (there is a fairly substantial number).

Is it best to use the CSV import tool in this case? Is there a way to export user accounts + passwords and import onto the new server without having to reset passwords? Or does the ACS migration tool have the flexibility to not overwrite user passwords or move selected accounts over?

Thanks,

Matt
