We are working on migrating our ArcGIS infrastructure to 10 and are having trouble identifying the impact moving SDE to 10 will have on our existing ArcPad Applications. We currently have 57 ArcPad licenses ranging from ArcPad 6 through ArcPad 8. My questions are: Can we still use previous versions of ArcPad with ArcSDe 10? If we decide to upgrade to ArcPad 10, what is the impact of that to our existing ArcPad forms and customizations? Will everything need to be rewritten or can ArcPad 10 read older forms? is the ArcPad code extension available in ArcPad 10?
