[c-nsp] 12.0 IOS still the preferred service provider train?

[Smith, Tracy L]

Hi.  We're a small service provider with 12410s in the core, which have
been running the 12.0 train for quite some time.  Is this still the
preferred service provider IOS train?

 

Additionally, we only upgrade when there's a new feature that we need or
when we've stumbled across an IOS bug and/or security advisory.  What
other best practices are people turning to when upgrading IOS?

 

Thanks much for the feedback!
