JDE min amount of ESUs to migrate to 64bit

Hi,

We are now + 280 ESUS, ..I want to minimize changes; we need to know the minimum number of ESUs required so we can keep modifications to a minimum, Which are the essential ESUs to install so that JDE run on 64bits?

or we want to reduce the number of ESUs to be installed—installing only those necessary to compile the full package and nothing else, How do we reduce the number of ESUs, .. The modules we want to exclude are 00, 03, 04, 09, 41, 42, 43, and 12; how can we exclude the ESUs containing these modules so they aren't installed? Which ESUs are they?

thanks in advance
