You are right.  There are no documents available detailing steps to upgrade from 1.x to 3.x.   To be completely safe I would recommend stepping up thru the 1.x levels then once you get to the 2.x level you can follow the steps laid out in the PDF - PC6200UpgradeSoftwareFromVersion2.xProcedure Here are the 1.x levels in order V1.0.2.6  --  www.dell.com/.../powerconnect-6248 V1.0.4.3  ==  www.dell.com/.../powerconnect-6248 V2.0.0.12  --  www.dell.com/.../powerconnect-6248 Hope this helps,
How should I go about upgrading my pc6248 from 1.0.0.27 to latest - 3.4.1.7?  I can't find anything online and the release notes have upgrade from 2.x.x. to lastest.   TIA,   Greg
