Esa to universal

Hia I live in Scotland I recently changed over to universal credit from esa I get adult disability each month I'm wondering will I get the same amount on universal credit as I was getting the premium on esa.i only changed over yesterday and handed id in and was told I'd get a payment in August I won't find out until the 6 August how much I will be getting this whole change over has been stressful. I know I can get a loan on universal but I'm hesitant to apply for it until I know how much I will recieve in payment has anyone else had experience in this.not sure how the process works as I'm in Scotland
