using CiviCRM 4.4.14. We're trying to update memberships with an import using data from a direct debit processor. In field mapping we're matching the pay out date to 'Membership start date', but some how this is also updating 'Member Since Date' too, despite not mapping this bit.
We really don't want this to happen as we loose how many years someone has been a member and the membership status then sets it's self to 'New'.
It was suggested that we use the start date of the payment plan as the 'Member Since' date, but this would loose any info about memberships that started using a different payment method (i.e. all of them!)
Any help greatly appreciated! Nicola
