Narrative:

Several VFR targets not talking to ATC added to the workload. At the time I had multiple traffic calls for IFR aircraft about VFR's. Aircraft X was level at FL060 direct yeagr. Uim-left 83 called with a point out landing tyr and a trl departure VFR looking to pick up IFR. I advised the controller of my traffic at FL060 and told them to stop their departure at FL050. The controlled later relayed that he could not get aircraft Y stopped. I saw the VFR target and called traffic to aircraft X. When I observed aircraft Y at 060 and merged with aircraft X I advised aircraft X of this and they stated the aircraft had just missed them. Later clear of traffic I asked aircraft Y how close the cirrus was and they advised they missed by about 100 yards. More attention to traffic calls; I feel that if the uim controller had called the traffic to his VFR departure they would not have climbed through my IFR traffic.

Narrative: Several VFR targets not talking to ATC added to the workload. At the time I had multiple traffic calls for IFR aircraft about VFR's. Aircraft X was level at FL060 direct YEAGR. UIM-L 83 called with a point out landing TYR and a TRL departure VFR looking to pick up IFR. I advised the controller of my traffic at FL060 and told them to stop their departure at FL050.
