Upgrade to ECC 6.0 from 4.7 - When to execute SPDD/SPAU

Hi Expert,

I'm doing technical upgrade from 4.7 to ECC 6.0 and just discover notes that related to activating Add-ons (Business Switch) for DIMP. It seems like some of the switch need to be turn on manually. The question is, should this switch be turned on before SPDD/SPAU or I can run SPDD/SPAU then turn on the switch? I'm raising this question because I notice some of the collective search help that contain customized elementary search help become resetted and the customized search help is not included in the standard search help anymore. Thanks in advance for the answer.

Rgrds,

Abraham
