Change of Employment - Tier 2 ( same Employer)

Hi,
My question is regarding this excerpt from Tier 2 and 5 version 04/15
39.39 Where a sponsored migrant must make a ‘change of employment’ application, you
must first carry out a resident labour market test (if this guidance requires it) before you
assign a new CoS to them. For example, if a migrant you are already sponsoring under
Tier 2 (General) wants to continue working for you, but in a different occupation which is in
a different SOC code to the one you quoted on their original CoS. You can’t simply give
them the job and assign a new CoS to them straight away unless there is an exemption
from the resident labour market test.t.

If application is new as provided, will the last leave be regarded as Tier 2 ( General) subject to RMLT or will there be a reversion to the tier before the initial grant of leave e.g Tier 4 or PSW.

Thanks

Your last leave will be T2 General subject to RLMT.
