Upgrade DSC Power 632

I just purchased my vera lite and want to upgrade my alarm panel so I can easily integrate with vera. I am thinking I’ll buy the PC1864. Will I only need to buy the new alarm panel plus the evl-3 to make this happen? In other words, I assume I will be able to use the same keypad, plug-in transformer, existing sensors, etc.

Do I have that right?

Thanks for your help.

If the 632 is still working then it should work with the plugin and you’d only need to buy the EVL-3
