If a temporary or evaluation StarTeam license is added to a server with an existing BLS or FlexLM license, the additional licenses on the temporary license cannot be assigned to users and this error is displayed:
An evaluation license already exists. Please delete it before proceeding.
This is expected behavior. A temporary native StarTeam license cannot be added to a permanent native, BLS or FlexLM license. A temporary or evaluation license key also cannot be added to an existing temporary license to increase the available user count.
