If upgrading any SMS to R80.20 or later, I'd strongly recommend doing an advanced database migration (migrate export/import), even if you are not moving it to a new piece of SMS hardware. This path will allow you to leverage the new 3.10 kernel with XFS filesystems. An in-place upgrade will retain the old 2.6.18 kernel and ext3 file systems, and will probably take forever on an underpowered machine like a Smart-1 210 anyway.
Really not a good idea to run an SMS and SmartEvent on a Smart-1 210 from a performance perspective, but we seem to have beaten that dead horse enough in this thread:
