Options for upgrading from Magento CE 1.6 to CE 1.9 and bringing customer records across

Question

I have a 2.5 year old Magento CE 1.6 site that I would like to upgrade to CE 1.9.

Due to changes within a number of areas - theme, extensions I am using, attribute sets etc. - I am in the process of starting from scratch on the Magento CE 1.9 site.

The only issue I have is that I want the customer records to come across to the new site without resetting their passwords.

From what I can see the encryption method of the customer passwords has changed from 1.6 to 1.9, so even with the same encryption key, I am not sure if this would work.

Is this, in any way, possible?

You can simply upgrade the database and capture all your data without any migration. If you follow the steps here

You will upgrade using a fresh version of Magento 1.9. Then you can move in any modules you still need/want.

You can then style you theme from the included Responsive theme in 1.9
