It's still Ctrl-C and Ctrl-V!
(sorry)
This is just a guess, but I'm assuming it would work like this:
Let's call the file that you export from your own profile File 1 and the file that your RT exports for you File 2.
I assume File 1 contains a long series of records for the daily data, but has a "hole" in the series where the 6 mos of missing data should be.
Similarly, File 2 has a long series of records for the six months of data.
If you examine the records and compare one record (which might consist of a whole bunch of XML "fields"--actually called "elements") in File 1 with a record in File 2. If there's anything in the records that identify the patient (patient ID, patient number, name, or whatever), then you'll have to Find & Replace All to make the identifier in File 2 match File 1.
Then examine the date ranges carefully and copy all of the records for the target date range from File 2 and paste them into File 1.
If you're right about the amount of data, you might have to press Ctrl-V real hard.
Back up all of your data first and only fiddle around with copies of the files.
If the records aren't easy for you to read at first, Google some articles that explain basic XML concepts. And if the records aren't nicely formatted and indented (which makes a HUGE difference), then Google for a good "xmllint" utility that will parse and format the records for you.
