what is the easiest way to transfer shareoint site along with workflows and people and groups content and all lists contents from one server to other
i tried saving site as template stp with include all content but the workflows are not working anymore and the people and groups are also not replicated on the new server.
Try exporting the site using stsadm.exe -o export. Use the parameter -includeusersecurity. Are you moving to a different farm? Different domain?
stsadm -o backup -url http://oldportal -filename C:\oldportal.dat
take the .dat to the new server, create a new WebApplication with a Blank Site Collection
stsadm -o restore -url http://newportal -filename C:\oldportal.dat -overwrite
Custom Features and Solutions won't get transfered, but the items you mentioned (workflows, people, groups) will all be transfered.
