1. INSTALL NOTES
1.1 Entering New Activation Codes
If upgrading from 5.1.x or below, new activation codes must be
entered. GB-OS version 5.2.6 is available at no charge to
customers with a GTA support contract or annual maintenance
agreement. Other users should contact their local Authorized GTA
Channel Partner or email sales@gta.com for information and pricing
of upgrade options.
1.2 Upgrade Notes
1.2.1 Re-sizing Slices and Runtime Upgrades
In order to support the new features in GB-OS 5.2 and above,
some firewalls may require partition re-sizing during the
upgrade process. Upon re-sizing, both runtime slices will have
GB-OS 5.2.6, and firewall administrators WILL NOT be able to
revert to previous runtimes via the Console or Web interface.
GTA strongly recommends backing up current firewall
configurations PRIOR to upgrading.
Firewalls requiring re-sized partitions will take approximately
5-8 minutes to reboot and fully update once the runtime has
been applied. DO NOT switch off or reboot the firewall during
this process.
1.2.2 Error Messages Upon Initial Reboot
Upon rebooting after successful installation, the GTA
Firewall UTM Appliance may display errors when accessed
using the Web interface. This is expected, these errors are
generated because the browser's cache is trying to access
files and locations that no longer apply. Click OK to any
displayed errors and refresh the browser window to access
GB-OS 5.2.6. If the error messages persist, clear your
browser's cache.
1.3 SSL Certificate Replacement
GB-OS version 5.2.6 will install a new default security/SSL
certificate. Some browsers, including Netscape and Mozilla,
will not recognize the new certificate if the original has
never been replaced. If you are unable to log on to the
firewall after upgrading, delete the browser's cached security
certificate, then close and restart your browser before
reattempting remote access to your firewall.
1.4 Mail Sentinel Anti-Virus
Since the release of GB-OS version 5.1.2, Mail Sentinel Anti-Virus is
no longer available as a separate subscription option. Mail Sentinel
Anti-Virus is included as a standard feature with valid support
contracts.
