Procedure describing CRS1 to CRS3 upgrade

[claudiols]

Hi all, please, is there a document describing the procedure to upgrade a CRS1 to a CRS3 (upgrade software, firmware, replace fan and fabric card)?

[Nicolas Fevrier · Accepted solution]

Hi,

could you please tell us what is the current version and the targeted version ?

Several links may be useful but it really depends on your "from" and "to".
