How do I merge two teams into one team?

To merge one team you will keep one and delete the other.

First choose which of the two teams you will keep. This is your primary team.

Go to teams & families

Search the team that will be disbanded (not the primary team).

Select manage

For each team member select the icon "move to another group".

On the next screen select the group that you are moving to from the drop down list

Once all members are moved the team will automatically be deleted.

All done!
