IFATCA Policy is:

Previous training, qualifications and experience attained by military air traffic controllers, should be assessed by the appropriate licensing authority and, if relevant, be credited towards the training required to meet at least ICAO Annex 1 requirements for attaining a civilian air traffic control licence.

If the military air traffic controller’s previous training, qualifications and experience meet at least ICAO Annex 1 requirements, then the appropriate licensing authority should facilitate the conversion to a civilian air traffic controller licence.
