I have already done this.
UK pension fund, QROPS from the UK to Malta (Malta is EU and aligns very closely with UK pension regs). Once I get to 55 I will transfer the cash from Malta to France with a single figure tax charge and then the rest is tax free, well worth doing
You are entering a very specific area of expertise and would be wise to take advice particularly as HMRC check this stuff very closely.
I used an independent adviser in France and then I managed the transfer of the funds from the UK to the new arrangement, it isn't technically a pension per se rather a bond within a pension type wrapper.
Depending on your own knowledge of pensions get some free advice.
Google QROPS transfer + your destination country.
