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. Remove all rrd-database tuples regarding Cricket (manually DELETE FROM rrd_file WHERE subsystem='cricket'; or with run_before_upgrading_to_3.6.py)
  4. Remove old temperature datasources from the rrd-files as they are removed in the new Default files (with migrate_cricket.py).
  5. Before removing any Cricket files make sure you have a backup of them. Especially if you have altered them yourself in any way.
  6. Remove old configuration-files from the cricket-config directory (it is highly recommended to do this for the top level Defaults file aswell). This is only necessary for the following directories:
    • routers/
    • router-interfaces/
    • switches/
    • switch-ports/
  7. Copy new default configuration files to the cricket-config directory.
  8. Make sure that the datapath in the top level Defaults-file is correct and pointing to the directory where the rrd-files are stored.
  9. 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.
