The packer system includes a packer mandrel, an upper support or gage ring, a seal member, an upper slip device, an upper cone, a lower cone, a lower slip device, a setting sleeve, and a setting piston. The seal member has a run-in position and a set position. The set position seals against a borehole at a location in a borehole. The setting sleeve has a bypass position to transfer load of the setting piston away from the lower slip device and to the lower cone, the seal member, and the upper cone to set the seal member and upper slip device before the lower slip device. The setting sleeve has a released position to separate from the setting piston so that the load of the setting piston can finally be applied on the lower slip device for expansion of the lower slip device at the proper time and location.
