The number of activation/deactivation operations is not effectively limited for manual license transfer scenarios. 

However, the technical possibility to transfer a node-locked license to a new computer should not be exploited in automated scenarios involving activation/deactivation of the license on regular basis. Excessive usage of activation/deactivation mechanism may result in the situation when the user gets blocked in the activation system. 

For scenarios that involve virtual machines and frequent license activation/deactivation operations, it is recommended to consider floating license option, in which case the license is automatically returned to the license server when the application (Metashape Professional) is stopped or the related process is killed unexpectedly.
