Remove DOC/DPF unit from truck.
Duck tape your shop vac to the inlet end of the unit.
Attach some 1/4 in nylon air line to a compressed air trigger nozzle
Apply puffs of compressed air to the DPF from the outlet side to blow the stored ash into the suction of the shop vac.
Dispose of the ash in landfill.
Don't breath this stuff during the process.

From what I've read about the DPF cleaning machines, the procedure involves heating the DPF to a very high temperature, applying extreme suction to one side and both pinpoint and pulsed air blasts to the other. The machines can also tell the operator to what % level the DPF has been restored.
The DPF's also need to be inspected for damage that would render them unusable, such as cracking or melting.
I wonder how effective the shop vac/compressed air method really is?

That's my understanding of what a true off-vehicle DPF cleaning does.
