NMIS9 installer will automatically import all nodes from NMIS8, however, some of the custom configuration won't be imported to NMIS9. In order to do that, a few extra steps are required.
Step by step
1. Install nmis (if not already installed)
# read and answer the prompts, checking carefully the selections work for your environment.
# NMIS does have good default selections and if you have tested those default selections before you can use -- -y to automatically select yes for all.
# nmis9-9.1.1.run should be replaced with correct version you elect to run.
2. Stop nmis8 and nmis9 from running
mv /etc/cron.d/nmis /tmp/nmis.cron
systemctl stop nmis9d.service
3. Replace the new default NMIS9 var/ and database/ directories for the old custom ones (NMIS8) by copying in the current data.
After migration you would consider removing the nmis8 directories and the old copies of the data.
rm -rf /usr/local/nmis9/database
rm -rf /usr/local/nmis9/var
cp -arfT /usr/local/nmis8/var /usr/local/nmis9/var
cp -arfT /usr/local/nmis8/database /usr/local/nmis9/database
4. Click here to download the import-nmis8-config.sh script and run it
5. Use the nmis-cli tool to fix the permissions
6. Lastly, start and verify nmis9d is running
systemctl start nmis9d.service
systemctl status nmis9d.service
