On September 6, 2016, Symantec VIP Authentication Service will perform three network security improvements:
Migrate three SSL certificates From SHA-1 To SHA-2 on symantec.com end-points.
Disable support for weak cryptographic cipher suites (algorithms)
Disable support for the SSL 3.0 protocol
***It is imperative that VIP Enterprise Gateway 9.0 or 9.1 (or earlier) is upgraded to VIP Enterprise Gateway 9.1.1 (or later) by September 16, 2016. Failing to upgrade will result in loss of connectivity when the migration occurs.***
VIP EG 9.0 should be upgraded to 9.1. 9.1 should then be patched 9.1.1.
