This is going to be a bit more complicated than I thought.
Rather than trying to give you step by step instructions, I am going to have to explain the principle, the tools and what you need to do.
What I am going to suggest is not without risk.You could make a real mess of things so BACKUP first.
The general principle is that the nominal data that appears to be wrong can be imported into line 50, so we can fix the numbers externally using the good data form the archive and then, using the import facility, load it all back in again to the current year.
What we will create is a spreadsheet, you can use open office, excel or whatever you are familiar with.
The sheet will contain the nominal code, its description and then sets of twelve columns for budgets and then the prior year(s).
So you will have a lot of columns and a lot of numbers and it could get very mixed up.
Rather than type all the numbers in ourselves we will cheat, we will get the numbers out of Sage alter them and then put them back.
(Actually we will get the number out of Sage a couple of times, from the current year data to get the budgets and from the previous year archive to get the good data for previous years).
We can combine these to create a "good" set of data for the current year and then import it back into Sage.
If you are happy with this and you understand what I am talking about then go for it, if you don't then you will have to pay us to do it for you or get someone else to help (Sage tech support?)
You need to decide with these files which one will be the master, are you going to use the archive data and add in the budgets and new accounts from this year or use this years data and add in the information from last year.
I would be inclined to use this years data and the vlookup function in excel to find the corresponding correct data in the archive. (you could cut and paste very carefully if you wanted.
First we dump the data out of the current year sage nominal ledger by printing the report Ni_ledg2.srt Reports>Nominal Details>Nominal Record CSV Extended. This is a handy format report because it create a file that is in the right format for a nominal import, so all we have to do is fix the data and we have it made. When you print the report print it to file and choose the csv file type, the file it creates you can open in your spreadsheet program "as" a spreadsheet.
It is worth nothing the field orders they are listed here

Version 11 and later is much more complicated they go back 5 years!
This will become our master file that we will import back into sage later.
We need to know the good data for the prior year so in the archive run the nomvals.srt report to file and set it to csv.
With both these files open in your spreadsheet program you can cut past or lookup current information from the previous year to correct the prior year information in the current year.
Once you have the corrections done, save the file (Note that excel has some quirks with csv format see below

Now import the "fixed" data back into Sage with File>Import
