Update Lumension EndPoint to HEAT EndPoint

I have Server 2008 R2 running Lumension Enspoint Security server.
It is using "Microsoft SQL Server 2008 R2" as database.
I am going to update Lumension Endpoint Security 4.6 to HEAT EndPoint Security 5.0.0

These are the main guidelines I do to update server:

• Turn Off server
• Create a snapshot
• Turn on server
• Log on into Lumension server with user which is used by "SQL Server" Service
• Unload antivirus
• Extract EndpointSecurity_5.0.0.zip

• Install content inside db directory

• Install smc
