It will be much easier to grow new grass.

You can do it, but I don't know how you'd manage it - you need a turfing iron or a machine which will cut and lift the turf for you - it then needs to be rolled and transported immediately, and where you live, because its hot, will need to be re-laid the same day on an area which has already been prepared to receive the turf, and then watering thoroughly. I'm not sure how you could achieve that, because it would mean having access to the new property a fortnight before you move in to prepare the area for the lawn.

If it's ornamental grasses and not the lawn, then you could pot them up and take them with you. It's a good idea to 'give' them to a friend to look after until you've moved. Removal men are not very careful!!

Assuming it's lawn grass, I think Bamboo has the right idea! The only thing that I would add is that there should be at least a month of warm nights before winter when you move it, if it is a tropical grass like bermuda. I don't know how cold the nights get there in the United Arab Emirates, but temps below 13 deg. C will cause the grass to go dormant, and not grow roots.
