That sounds horrifically laborious.

I upgraded a 9001 from 4.3.2 to 5.3.1 in one hit. No need to TurboBoot,
no mass reconfiguration.

Any configuration changes were extremely minimal. The guides (PDFs) at
http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html were very
quite thorough, I must say.

I've done it since then too, with an RSP-440. It was only 5.1.3 to 5.3.2
that time, but it was just as painless.
