Can we skip to the latest Vijeo Designer Service Pack?

Yes. Vijeo Designer Service Packs are cumulative so Vijeo Designer VX.y SPz would contain the same fixes as Vijeo Designer VX.y SP(z-1)

Ex. Vijeo Designer V6.2 SP3 contains Vijeo Designer V6.2 SP2 and Vijeo Designer V6.2 SP1.

Keep in mind that it is possible that some hotfixes are not in the service pack that is immediately next (ie version SPn). This is indicated by a build number of 5000 or greater for the hotfix. The hotfix content in this case will be available in the next service pack (ie. SPn + 1)
