Thank you for visiting the QuickBooks Community, chrizaan-creativ. I'll share some insights on how the QuickBooks region works. Let me also point you to the right support team to assist you further with your concern and ensure you can accomplish your goal.
Please know that the account’s region is set by the region’s website in which the QuickBooks Online subscription was made. Thus, changing the Online profile's country from the United Kingdom to Ireland is currently unavailable.
Since you've mentioned about MoveMyBooks app, it seems you're transferring your data from one software to another. With this, I recommend contacting their Support Team to ask and confirm whether the option you require or need is available on their end.
Lastly, if you need guidelines for effectively managing your business using QBO: Help guides for QuickBooks Online. It contains topics about advanced accounting, banking, and payments to name a few.
