@AlexKeysMusic:
Hi,
the EZD1 to EZD2 upgrade was discontinued on December 31 2015.
You would need to buy a full license now.
The EZdrummer 2 plugin replaces the EZdrummer 1 plugin on your system but it does not recall the EZdrummer 1 settings saved on host songs.
It can read the EZdrummer 1 mixer presets for older EZX:s.
EZdrummer 2 can both load the EZdrummer 1 core POP/ROCK EZX and any other EZdrummer 1 EZX:s you have installed but they need to be updated.
BR,
John
