I was working west departure combined with east departure. I accepted a point out from X position on Aircraft Y going to ZZZZ intersection. I stopped Aircraft X at 12;000. I noticed that Aircraft Y was level at 12;000 converging with Aircraft X. I climbed Aircraft X to 13;000 and assigned a frequency change to Center. After he switched frequencies; I recognized Aircraft Y began to climb. I notified the X controller that I had already changed Aircraft X's frequency. Coordination was made with Center that Aircraft X was their control.My recommendation is that east and west departure be de-combined early enough as to not have the position overloaded.
[Report narrative contained no additional information.]
Three TRACON controllers reported that two aircraft at the same altitude on converging courses both started to climb with possible loss of separation.
