Introduction

This document contains information about upgrading from previous version of NAV to 3.6.

Cricket

After the upgrade the following steps are required:

  1. Make sure Cricket is not running.
  2. Do a backup of all the rrd-files.
  3. Run migrate_cricket.py. This will:
    • Delete the cricket-entries in the rrd database (the database will be filled again when the new makecricketconfig runs)
    • Remove any temperature oids from the rrd-files. This because they weren't correct in the first place.
  4. Before removing any Cricket files make sure you have a backup of them. Especially if you have altered them yourself in any way.
  5. Remove old configuration-files from the cricket-config directory. This is only necessary for:
    • Defaults
    • routers/Defaults
    • router-interfaces/Defaults
    • switches/Defaults
    • switch-ports/Defaults
  6. Copy new default configuration files to the cricket-config directory.
  7. Make sure that the datapath in the top level Defaults-file is correct and pointing to the directory where the rrd-files are stored.
  8. Run extract_cricket_oids.py to extract oids from the Default files and insert them into the snmpoid table.

You can now run mcc.py to create the Cricket config.
