Hello. Can i safely upgrade Plesk Version 12.5.30 to Plesk 17.8.11. The Install and Update Plesk page does not give me the option to start the upgrade step by step from older version to newer versions. Thanks
Also, please make sure you create a backup and/or snapshot before upgrading. My upgrades from Plesk 17.8 to 18 failed a couple of times for some reason.
