[Dragoljub Spasojevic]

Hi,

where I can find detailed ISSU upgrade procedure for ASR9k from 5.1.3 to 6.2.3 anc CRS from 6.1.3 to 6.2.3.

Thanks in advance.

Zdravo Dragoljube,

ISSU support on classic (i.e. 32-bit) IOS XR was deprecated in 5.x releases.

ISSU support comes on the enhanced (i.e. 64-bit) IOS XR, starting with IOS XR release 6.2.3. This release is the first EMR from which you can perform an ISSU upgrade. Please refer to:

Pozdrav,
