1.4   Known issues after upgrade

a) Because Bitdefender Management Console dashboard was redesigned, you will first need to configure it by selecting the exact sections you want to have as active; in order to view how to configure the dashboard sections, you will need to access KB821 article;
b) The Bitdefender Business Client Update Scheduled policy was renamed and therefore it will not exist in your migrated policies list; We strongly recommend to apply a new "Update Settings" policy with the new settings;
c) The existing Scheduled Reports are lost during upgrade;
d) The existing policies called "Antivirus Settings" for Bitdefender Security for Exchange Servers  and Bitdefender Security for Mail Servers are lost;
e) The existing policies called "Filtering Settings" for Bitdefender Security for Mail Servers are lost;
f)  Because Bitdefender Master-Slave architecture was redesigned, you will need to upgrade both master and slaves servers from your network; else, the slave server replication won't be recognized by the master server;
g)  If you are using MAC products integrated with Bitdefender Management Server, the machines will appear as unregistered in the "License and Password Status";
