RE: Migration from Version 8 of Great Plains
As has been mentioned, to upgrade Great Plains 8.0 to a newer version of Dynamics GP, you're looking at something like:
v8.0 > GP 10.0 > GP 2013 > GP 2016 > GP 2018/18.2
This doesn't take into account the SQL versions to be used for this potential 4 step upgrade path, and that is also with the assumption the Great Plains 8.0 is on MS SQL Server, which usually it is.
In newer versions of Dynamics GP, there is a migration functionality to go to D365, but D365 is not Dynamics GP, it's more Dynamics NAV and Dynamics CRM than GP.
We don't have any migration functionality to go from Dynamics GP to QuickBooks.
Let us know if you have any questions.
Thanks
