Downgrade from Enterprise Edition to RAW Edition

General

Hi,
our customer decided to not “renew” the Enterprise edition so we have to switch back to RAW edition.
I’ve looked on the forum but I don’t see the option to downgrade: Updates and Upgrades

Anyone has idea if is possible to do it?
Thanks in advance.

Not guaranteed to be a complete list:

  • check if you have CEE only rules. i.e. rrd settings using the single file option, recurring host/svc downtimes, bakery rules and remove them
  • stop the site
  • if you used the CEE rrd format, I suppose you also have to use “cmk --convert-rrds” to make them pnp4nagios compatible again.
  • switch the monitoring core to nagios
  • install CRE (ideally of the same Release as the current CEE, to ensure that possible errors you encouter are only CEE vs. CRE) and use “omd update ” to switch over to CRE

using omd config if I may add. :slight_smile:

I think you need also configure RRD databases if you not longer uses the cmc.

Just for my understanding…as i am quite new to the Forum and happy to work with the Enterprise Edition for several years. What are typical reason to went back to the RAW Edition ? Any thoughts from your exerience as cmk partners welcome :slight_smile: When compare enterprise prices with other vendors like datadog…then CEE is not that expensive for a company

I think money is the only reason, at least I don’t know any other CRE advantage.

Hi @joerg.mohar

in 99% of cases the reason is money. Budget goes away, or (very rarely) the customer does not see the value they are paying for.

I recently had one prospect where they can ONLY use completely OSS where they can see the entire source code.

I recently saw another case, albeit quite special:

The CEE failed an internal compliance assessment, because there was a requirement that as soon as a software offers an upload function, there must be a hook to trigger an immediate virus scan. The customer found no easy way to implement this for the upload of extension packages.

So the solution was a migration to the CRE which offers no upload function for extension packages in the GUI.

don’t most linux antivirus scanners use fanotify to be informed about any file read/write action? I’d have assumed that subscribing to fanotify events for /omd/sites//var/check_mk/packages_local/ for any file placed there would have the same affect as running a hook.

Hi. In all our installations in private, public or defence enviroments there are no security concerns relatet to this feature.

…or just use an icap capable reverse proxy hooked up to a AV scanner.
