In G5 you can merge two Households together or two Contacts together.
If you have duplicate individuals inside duplicate Households, the best practice is to merge the duplicate Contacts first, then merge the Households.
Go to the Contact Workspace, Select Contacts and type the name of the Contact you want to merge in the search bar.
Click the More Actions button to the right of the Contact and select Merge Into…
Select the Contact you would like to merge the first Contact into. Click OK.
Note:
A batch process will begin to perform the merge. Click Continue.
You will receive a notification when it is complete:
Go to the Contact Workspace, select Households and type the name of the Household you would like to merge in the search bar.
Change the Head of Household to a different role. Each Household can only have one Head of Household. Decide this before merging to avoid any errors during the merge.
Do the same thing with spouse, so that between the two Households there is only one spouse.
Click the More Actions button to the right of the Household and select Merge Into…
Select the Household you want the first one merged into. Click OK.
Note:
A batch process will begin to perform the merge. Click Continue.
