Limitations of the Upgrade


The application relies on new licensing scheme in all versions higher than 6.0. Valid license keys from versions less than 6.0 are NOT COMPATIBLE. Please contact to convert your valid license key into new format free of charge.

The following limitations are present.

  • Unfortunately we cannot upgrade the collected traffic in monitoring database.
  • Squid authentication settings are only partially upgraded. Please manually reconfigure Active Directory integration and enable Kerberos/NTLM/Basic LDAP authenticators if those were configured before.
  • Credentials for the root user in UI are reverted to default. All users added to UI are lost.
  • You may need to manually re-import existing license key, RootCA certificate and keytab file into UI again.
