Well, if you want to relocate your MA in Sweden you will need to rebuild a grand mosque, an university and a MA in the new province (I assume that you already have a fortress in the new province ...) so that it will take you quite a few years (36 if I remember correctly: 16for the grand mosque, 10 for the university and 10 for the MA itself). You might also have to add the time necessary to build the Master Bowyer (for Janissary Archer) or the Master Spearmaker (for JHI) so that you have good chance to end up with no Janissary at all for something like 50 years.

The above is not correct if you can destroy your Grand Mosque and university while still remaining able to build JHI in Palestine thanks to your existing MA. In that case the gap would be 10 years (the time necessary for the new MA after you've built all other facilities required for JHI in the new province) and you just loose the morale bonus granted by the Grand Mosque for a while - no big deal for JHI. I cannot confirm whether that is an option but that something that you can easily check in your current campaign). Just check whether you can build an new MA without destroying the old one. I am quite sure that you cannot have to cathedral or grand mosque but I am not 100% sure regarding MA (might be tempting then to build/destroy Grand Mosque just for the purpose of completing a MA).

Do note that Janissary Archers get a valour bonus in Georgia while JHI get one in Bulgaria so that you might want to consider what is the best location for you new MA.

Hope it helps.
