Hi Eyals1,
You would need to cancel your individual membership and rejoin with a team type membership, cancellation fees would be waived for transition. It would require contacting our sales department who could assist you with the process. I'd recommend learning more about the teams option first. It is more expensive. There is a section in the Creative Cloud FAQ, the Creative Cloud for teams section that has a lot of useful info.
