UC information?

I am on ESA Support, the area I am in is due to go over to UC at end of year, I understand that when it dose and I get migrated, assuming I am assessed correctly I will get the same income as ESA Support group? but on the UC instead? Is that right. But I have opportunity to move to more suitable housing, that is in a different county council area, they are to be fully UC next month, my move, if it goes ahead would be after new area becomes fully UC. I have read that if I move into a fully UC area, that although I am now on ESA Support, because I am moving, rather than they transferring me onto UC, I will not get the gaurranteed same amount of money, but will loose about £50 per week? Is this so. Tying to find information on this is so hard. Also claiming UC I understand is on line? Do they do the disability bit of UC on line as well? Please can you explain how the UC is going to work. I also read that even though I am in the support group, under UC I will then have to attend the job Center, disbit being in support group, is this so? I’m worried, maybe I’d be better to not move, I know I will be mirgrated at end of year anyway, but if I loose out financially by moving to another area to get more suitable housing, why would that mean I loose money,just because new area has already become fully UC, I’m confused?
