Upgrading the SnapCenter Server

You can use the SnapCenter Server installer executable file to upgrade the SnapCenter Server. You can upgrade either from SnapCenter 4.0 or 4.1.x to SnapCenter 4.2 or 4.2.1.

Before you begin

About this task

The upgrade procedure places the host in maintenance mode, which prevents the host from running any scheduled jobs.

Steps

  1. Download the SnapCenter Server installation package from the NetApp Support Site.
  2. In the left navigation pane, click Hosts., and in the Managed Hosts list, select the host that you want to upgrade.
  3. Create a copy of the web.config located at C:\Program Files\NetApp\SnapCenter WebApp.
  4. Export the SnapCenter schedules related to SnapCenter plug-in for Oracle host from windows task schedule so that you can use it to restore the schedules if upgrade fails.md d:\SCBackupschtasks /query /fo CSV /v >> "D:\SCBackup\sch.csv"
  5. Create the SnapCenter MySQL database dump if the repository backup is not configured.md d:\SCBackupmysqldump --all-databases --single-transaction --add-drop-database --triggers --routines --events -u root -p > D:\SCBackup\SCRepoBackup.dmp
    When prompted, enter the password.
  6. Initiate the SnapCenter Server upgrade by double-clicking the downloaded .exe file.
    After you initiate the upgrade, all the prechecks are performed, and if the minimum requirements are not met, appropriate error or warning messages are displayed. You can ignore the warning messages and proceed with the installation. However, errors should be fixed.
    Note: SnapCenter will continue to use the existing MySQL Server repository database password provided during installation of the earlier version of SnapCenter Server.
  7. Click Upgrade.
    At any stage if you click the Cancel button, the upgrade workflow will be cancelled. It will not rollback the SnapCenter Server to previous state.
  8. After the upgrade is successful, log in to SnapCenter and then, on the left navigation pane, click Hosts > Activate Schedule to bring the host out of maintenance mode so that operations can resume.

After you finish

Best Practice: You should either log out and then log into SnapCenter, or close and then open a new browser to access SnapCenter GUI.
