I made the switch in August, watched all the video stuff, read the manual, played with the animas pump before making the switch. I just used all the same basal, bolus, ratios and got started. I did call Animas tech support a couple of times, I was getting more air bubbles in the reservoir than I had with my Medtronic and was just making sure I wasn't doing something really wrong when filling (have figured it out now, no trouble), and I think I also questioned tech support regarding the differences in the pumps concerning changing the battery and when the reservoir hits "0" just to make sure I understood. I did not see my diabetic educator until about a month or so later and no changes were made at that time. I did keep the Medtronic pump set to "suspend" and hid it to where I wouldn't hear the reminder alerts just in case I had problems and had to switch back.
I just started pumping a 10 days ago and got the Ping because I had money left in my flexible spending and plan to use the $99 upgrade to the Vibe when available. Got the Dexcom also. As for the bubbles, my trainer was especially diligent in the training to ensure there was not even a film of air in the reservoir. When i flicked it, she said no, you need to use a pen or something harder to whack it to get them all out. Kept saying cant you wee them, and I was like that? There were two on the plunger that wouldn't amount to a period in this sentence if they joined all their friends. I was like whatever, but that was the advice i got.
I just had to get use to the difference in the reservoirs/length of the needles was my biggest problem. MM's needle is short and Animas is back to that huge and long one so with a not totally full vial of insulin I was "catching air" when filling. So I just go slow (like with MM) and watch placement of the needle in the insulin vial. Also, the "fit" of the vial on the MM reservoir is more solid compared to the Animas and that also took a little time to adapt to. I had it down pretty good by the 6th or 7th site change, and now do not seem to have any more trouble with air bubbles than I did when using MM - usually due to carelessness and trying to fill to quickly. And do be prepared for a little more button bashing with the Animas as compared to the MM. I use a lot of the Audio Bolus feature for speed now when I can instead of going through the carb bolus menu. And the One Touch Ping remote - that's nice too. And having to remember that cartridge cap - kept forgetting that was needed too when I began! Good luck. I'm sure you will do fine.
