Extra Street Address Fields


We are currently running SuiteCRM 8.3.1 but will soon upgrade to 8.4.0.

In the contact and target modules there is only a single street field i.e. “primary_address_street”

However in the UK we do need extra street fields for our addresses. How would I add “primary_address_street2” and “primary_address_street3” fields to both the target and contact modules? Is the process the same for versions 8.3.1 and 8.4.0 ?

Would the target import feature import the two new fields i.e. “primary_address_street2” and “primary_address_street3” by default or would further changes be needed ?

Would I loose the above customisations when I upgrade from SuiteCRM 8.3.1 to 8.4 ?
