It is possible to export all transactions as a .csv formatted file.
Using "Report > banking > transactions" you can generate a report (list) of all transactions.
This can be exported via "Print > Export to file > .prn (123) format"
You can customise this report for changing the date range, selecting split transactions or selecting hidden accounts etc. Review the options on each tab of the customise pop-up.
This can also include non-banking accounts, such as share accounts.
This can then be imported into Excel and should be able to be reformatted to a suitable format.
Note: I have found there is a limit of 32,000 transactions per report, so you could apply a date range to each report and collect the info in Excel. Open the file as a .csv file or do a data > convert to text, enabling a comma separator.
This approach applies to most transactions, giving a reliable independent format backup of all the data you have entered. Other information, such as share price history, can also be exported via a print to file function, although I have only found a single company report available. It may be easier to source prices elsewhere if this is required.
I do not know of a direct transfer format, which would depend on how you can import the information to the new package. This is a robust approach to obtain the transactions from RPP in an independent format.
