The new 2048-bit root updates will go live on:

Thawte(R) - June 27, 2010
GeoTrust(R) - July 22, 2010
VeriSign(R) - October, 2010
RapidSSL(R) - Fourth Quarter 2010

To adequately prepare for the root upgrades, we recommend that you
view the recorded webinar and do the following:

1. Review our test websites that use the 2048-bit root and new
intermediate certificates (see support advisory links below).
2. Communicate the root upgrades and go live dates to your internal
support teams.
3. Update your existing website and customer collateral with
information about installing intermediate CAs. We will also include installation instructions in fulfillment e-mails.
4. Communicate the new installation process to your customers.

NOTE: The installation process will change for all Thawte (excluding: SGC SuperCerts and Web
Server with EV Certificates) and GeoTrust certificates (excluding True BusinessID with EV, PowerServerID and RapidSSL Certificates) issued after the go live dates.
