Satellite Upgrade from 4.27 to 4.28

This guide will lead you through the steps specific for upgrading a NetEye Satellite installation from version 4.27 to 4.28.

Warning

Remember that you must upgrade sequentially without skipping versions, therefore an upgrade to 4.28 is possible only from 4.27; for example, if you have version 4.21, you must first upgrade to the 4.22, then 4.23, and so on.

Before starting an upgrade, you should read very carefully the latest release notes on NetEye’s blog and check out the features that will be changed or deprecated after the upgrade. You should check also the whole section Breaking Changes below.
