1) Cisco ISR 4000

Current version : Version 16.12.3

2) Cisco Catalyst 9400

Version 16.6.2r[FC1]

Thanks & Regards

Catalyst 9400 : https://software.cisco.com/download/home/286316710/type/282046477/release/Bengaluru-17.6.4 , in both case read the Release Notes of the targeted version(s), you will then find info's concerning the upgrade path and you will be able to make an estimate of the involved downtime(s)
