Steve,
This morning I implemented the changes to stop sending RUC GRIB1 and begin sending NAM awipak and grbgrd in GRIB2 as scheduled.

Steve,
Please work with Paula and Justin on the transition.  Sounds like a
nice slow pace is the way to go.

Joe,
Back in August, I mentioned that I would need to schedule a
transition of remaining grib1 products being sent on CONDUIT to grib2. 
I would like to begin by removing the RUC data currently being
sent in GRIB1 format. The same data is already being sent in GRIB2, and should remain. Concurrent with removing the grib1 RUC, or anytime available thereafter, I would like to add grib2 format NAM for the awipak and grbgrd data sets and let that overlap the existing grib1 data sets for those files for 2 weeks and then turn off the grib1 format data for those files after the the 
2 week period.
After removing the grib1 awipak and grbgrd data sets, I would then
ask to add the grib2 format data for the awip3d files and do a siimilar 2 
week overlap before removing the grib1 data.
That should clear out the RUC and NAM grib1 data. After that,
we'll decide what to do with the 1.0 degree GFS.
Can you see if the above can be fit into your time schedules? Let
me know if you have any questions or concerns!
Thanks,
Steve
