Do I need or it is better to reinstall the system under new hardware or it is just ok to plug hard drives in and run the server? I can manage small fixes if required. I would like to avoid reinstallation because I have already shrunk system partition and made other important partition on same drive. I do not want to lose it during the reinstallation and as far as I know, OMV takes entire drive space by default (not sure why...).
Thank you for your suggestions.
