Firmware updates can be conducted using the following methods:
Only for advanced users or system administrators:
1. Manual TFTP update: Exceptional situations or downgrade, see page 12
2. Manual update/downgrade: Most convenient when updating/downgrading within the
same major release level, e.g. 6.X: from version 6.2.3 to 6.5.10, etc.
L Note: We do not recommend manual updates between different major release
levels, e.g. from 3.X/4.X/5.X to 6.X or 6.X to 7.X. Use Æ automatic updates
instead.

release.
