Preparing to upgrade a shop from 1.37 to 1.51. Was hoping to migrate directly to 1.6 but can't wait any longer. Will be dropping Google Checkout support next month, so hoping to go with "PayPal Payments Advanced".

Dr Byte, I've just set-up a clean install of 1.51 on my server. If you need any assist testing your PP Pmts Advanced module code drop me a PM.
