To deploy policies:
1 Click Tools > Deploy to synchronize the EncrypTight components with the current policies. Note that 
this will interrupt traffic on the PEP briefly. 
Step 5: Upgrade PEP Software
After you upgrade the ETKMSs and ETPM, you can upgrade the PEPs to a new software version. Using 
ETEMS, you can download new software from an FTP server to one or many PEPs of the same product 
family. For example, ETEMS can upgrade a mix of ETEP models, such as ET0010As, ET0100As, and 
ET1000As, in a single operation. 
When upgrading software on ETEP 1.6 and later appliances, you have the option of using FTP or SFTP 
for secure file transfer. If you choose SFTP as the connection method, all of the selected appliances must 
support SFTP.

Upgrade remote appliances first when managing appliances in-line, where 
management traffic flows through the data path 
If you are managing your PEPs in-line as shown in 
upgrade in two stages. First, upgrade all the PEPs at remote sites and reboot them. When the remote site 
PEPs are up and operational, upgrade the local site PEP, which is co-located with the EncrypTight 
management station. Upgrading the local site PEP at the same time as the remote PEPs can cause 
connectivity with the management station to be lost and the remote site upgrades to fail.
