Is Upgrading Marketo Lead Management from AppExchange non-destructive?
I have discovered that the version of Marketo Lead Management in place in our SFDC org is from September 2012 and does not contain all of the fields that should be synced from Marketo, such as Acquisition Program Name. This shows as being mapped to mkto2__Acquisition_Program__c (SFDC Lead) and mkto2__Acquisition_Program__c (SFDC Contact); however, neither of these fields exist in the SFDC org. I am guessing that this is because the Marketo Lead Management was installed before these fields existed.
So, my question is, can we safely upgrade our Marketo Lead Management app without deleting any existing field data? I would hope so, but as I have to hand this to the IS team in the company to do (I'm not allowed to touch SFDC), I want to be sure before I request this.
