Upgrading SnapCenter Server 4.1.0 to 4.1.1P4

A lab run through of upgrading SnapCenter build 4.1.0.1341 to 4.1.1P4. Download link for SnapCenter 4.1.1P4 = https://mysupport.netapp.com/products/snapcenter/4.1.1P4/index.html

Note: This lab just has SnapCenter for Exchange running. Read the official documentation as I’ll skip some things not relevant to this lab scenario.

Official Documentation:
SnapCenter Software 4.1: Installation and Setup Guide
See page 170.


2) Create a copy of the web.config

Located at C:\Program Files\NetApp\SnapCenter WebApp

3) Create the SnapCenter MySQL database dump
(if the repository backup is not configured.)

md d:\SCBackup

mysqldump --all-databases --single-transaction --add-drop-database --triggers --routines --events -u root -p > D:\SCBackup\SCRepoBackup.dmp

When prompted, enter the password.

4) Run the downloaded .exe file to launch the SnapCenter upgrade wizard.

The log files are (where xxx is a timestamp):

5) Login to SnapCenter and Check the Version

About SnapCenter should say:
SnapCenter Server 4.1.1P4

6) Upgrade plugins

SnapCenter > Hosts > Managed Hosts
Select host
Click Modify

6.1) Modify: Select Upgrade plug-ins and click Next
6.2) Plug-ins: Make sure the correct Upgrade package is selected and click Next
6.3) Preinstall checks: click Next
6.4) Summary: click Finish

SnapCenter > Monitor > Jobs

Wait for the plugins to be upgraded.


THE END

Note: If your Dashboard headings don't display correctly after the upgrade, just reboot the SnapCenter server (that did the trick for me.)

Other tips (for upgrading SnapCenter plugins):

If a plugin is complaining that it cannot acquire information (cannot acquire .NET or PowerShell version so has red cross against their version status), rebooting the plug-in host server will fix this (restarting SnapCenter services does not fix.)

If the plugin appears to have installed (when checking the version on the plug-in host) but SnapCenter seems to be stuck on installing, try to manually update the plugin using the PowerShell in link [1] below:
