Switch from sensitive form back to regular?

DS has been on Similac Sensitive from about 4 wks old...at the time it really made a huge difference and my pedi told me he may outgrow the sensitivity and later we could try to switch him back to Similac Advance.  He has just started daycare where they provide formula until they are 1 year old.  They only provide Similac Advance...not the sensitive.  Just wondering if anyone has had any experience with switching back.  I would like to try but don't want to hurt his stomach.

We switched our LO back to Advanced from Sensitive about 3 weeks ago and he did fine. We mixed the two for about 5 days by weening him off sensitive and he did great! He was a little gassier at first but no colic or anything else.
