Hello! Thanks for reading my post.

My concern is that my team and I can't add a contact to a new household.  In doing some research, I found that I should check System Tools>Health Check.  It said that my Account Model Data says that we have a mixture of account types, and that all of our accounts should use the same Account Model.  

The Account Model is set to Household Account but a percentage of our accounts are on a one-to-one.  

Are any of you lovely people able to help me with this?  I can't figure out how to switch the one-to-one accounts to Household Accounts.

Thanks!
