I built a new form in Nintex Forms for Office 365 and put it into production and now a request was made by the users to be able to search and view their old forms previously completed in InfoPath 2010 on SharePoint on-prem.
What is the best option for this? Has anyone encountered this situation before?
There are over 6000 items from the previous version and I don't want to overload the new SharePoint Online list / library with old items.
I do have access to the important data stored in column, rather than have to parse through the InfoPath XML, so that is a plus, but I still don't know if I should move it into SharePoint Online. I am wondering if the best plan is to store that historic data in a data warehouse and keep it off SharePoint Online.
