Traffic Engineering router OS v7 issue

It’s a bummer. I am slowly running out of R0S6 Devices. Thankfully I still have some CCR1009-7Gs on the shelf with Ros6 for now. I bought a few RB4011 and they are stuck ros7 on them and no downgrade option luckily they were able to be returned. I am planning some larger multiband licensed links after which time I won’t need TE anymore. I’d really like to upgrade several sites to CCR2116s. But mostly stuck for now. They have been great in areas of the network that don’t need MPLS/VPLS RSVP-TE
