Introduction

This document describes the procedure to upgrade NCS1001 from SW 7.10.1 to 25.4.1.

Mandatory Bridge SMU installation in NCS1001 to Upgrade from 7.10.1 to 25.4.1

If customers upgrade the node from 7.10.1 to 25.4.1, they can see the issue of DISK space not available if these SMUs are not installed in 7.10.1.

ERROR! No enough space to proceed with ADD operation.

This issue is not because of the space and must be confirmed from CLI using the show media location all command if it shows enough free space. But, still the error was seen.
