Install a new ROM with APPS2SD on a new SDCARD

[Guest lambrospower]

Hello guys, i have a question, some may call it noob some may thought it themselves. i am currently rooted and using mcr3.1 without problems at all but i don't have the apps2sd.

i want to try it and i baked a new rom from the kitchen with the a2sd+ option integrated but i don't want to mess up my current sdcard and want to use another one i have. can i do that ???

as i see it i must do the following:

1) while my CurrentCard is inserted make a nandroid from the fake-flash recovery

2) turn off the phone and insert the new card

3) put the update.zip (for fake-flash) and the baked rom onto the sd card

4) now go into recovery (fake-flash) and choose to install new rom

will this work ok ?????

in addition as i see on my SDCARD some applications like titanium backup or astro or htc mail, rom manager, wifi tether etc have some files on it into their respective folders. will i be ok if i copy-paste them after the procedure into their folders in the fat partition???? or the a2sd+ uses some other m,ethod for the apps to store their info ????

THANKS for all the help
