UK Military ATC to Civil Licence Conversion (Split)
It isn't going to happen overnight.
Ineviatebly it will bring some compatibility into the system, but it'll be a number of years before ex Mil Atcos can just "convert" their licences into civil ones.
Significant differences still remain between they way the two sides operate at airfields and SRG will insist on courses and exams being undertaken until they're sure there's no margin for confusion.
