Moving customers passwords to new site 1.2.4.0->1.6.1.1
Hello, I was trying to upgrade my 1.2.4.0 to 1.6.1.1 .
I created a new site and migrated all the data using a payed service. All is well except for the customers passwords. The recomendation is for the customer to have to create a new password using the link. This is not something I want my customers to go through and if it was me I might have cancelled my order if I couldnt log in.
So I'm trying to move the salt and hashes and all that stuff from my old installation. Just moving COOKIE_KEY and COOKIE_IV doesnt help and then I cant login to the admin site either.
How Can i do in 1.6.1.1 version.
