Yes, you can migrate your data to Sage One. Bear in mind that your "Current" Pastel Xpress database only holds your current year and last years transactions, which is what would be converted to Sage One. Your historical databases are not generally taken over, so you need to keep your backups of those on the Xpress system. If you want to move everything to the cloud, there is an option to pay for additional companies on Sage One. You could then convert your historical data to a separate online database and access it that way. You will need to pay for the historical conversions, and pay for the extra databases each month, so it isn't a recommended route to follow. Once your Xpress license has expired, it will revert to view only mode. You will still be able to access the data and print reports, if required.
