I agree it is not the same as the old conversion, but I don't think it will require 30 hours of training in a SEP.
Microlights are not defined in the basic regulation or Part-FCL, so must come under the "aeroplanes", mentioned in FCL.110.A a).
Only 15 hours dual instruction are required in the class in which the skill test is to be taken, and 50% of those can be credited to pilots with previous PIC experience. That could mean that 7.5 hours are now required, rather than the previous 5 hours.
FCL.110.A LAPL(A) — Experience requirements and crediting
(a) Applicants for an LAPL(A) shall have completed at least 30 hours of flight instruction on aeroplanes or TMGs, including at least:
(1) 15 hours of dual flight instruction in the class in which the skill test will be taken;
(2) 6 hours of supervised solo flight time, including at least 3 hours of solo cross-country flight time with at least 1 cross-country flight of at least 150 km (80 NM), during which 1 full stop landing at an aerodrome different from the aerodrome of departure shall be made.
(b) Specific requirements for applicants holding an LAPL(S) with TMG extension. Applicants for an LAPL(A) holding an LAPL(S) with TMG extension shall have completed at least 21 hours of flight time on TMGs after the endorsement of the TMG extension and complied with the requirements of FCL.135.A(a) on aeroplanes.
(c) Crediting. Applicants with prior experience as PIC may be credited towards the requirements in (a).
The amount of credit shall be decided by the ATO where the pilot undergoes the training course, on the basis of a pre-entry flight test, but shall in any case:
(1) not exceed the total flight time as PIC;
(2) not exceed 50 % of the hours required in (a);
(3) not include the requirements of (a)(2).
