You wish to know the best course of action to take to upgrade your Symantec Endpoint Encryption Management Server to version 8.x from an earlier version of SEEMS or GEMS.
This article is intended as a brief overview. For more detailed instructions, please consult the Installation Guide provided with the software.
In general the upgrade process is unchanged. However there is a significant change to be aware of that will be an impact on any upgrade strategy:
The hashing function that applies to the Management Password and functions stored in the database has been upgraded from SHA1 to SHA2 64-byte as of SEE 8.0. Occasional issues have been seen when performing management operations, specifically the extraction of DAT files and operation of the OTP mechanism, on managed client machines running GEHD 9.X or SEE 7.x. This problem will not be encountered on clients that have been upgraded.
For that reason, it is advised to upgrade all clients to SEE 8.x as soon as possible after upgrading the server in order to be sure to avoid problems running these functions on clients running older versions of the product. The procedure is as follows:
Upgrade the Management Server by doubling clicking the Management Server installer.
Upgrade the Framework: msiexec /i <package> REINSTALL="All" REINSTALLMODE="vomus"
Upgrade Full Disk (if using): msiexec /i <package> REINSTALL="All" REINSTALLMODE="vomus"
