Hi Mikael, There is a process to downgrade, but it is not working for me
http://www.cisco.com/web/Cisco_IOS_XR_Software/pdf/CRS-1_Upgrade_Procedure_3_6_x_4_0_0_to_401-3.pdf I have 3.6.2 in production network and I want to move to 4.0.1 due to some really "GOOD" feature availability. I also think the last option is turboboot, if I do not find any other way to downgrade.
