KPMG LLP, Montvale, New Jersey ( 1999-2009

Manager ITS: Messaging Operations: Provided skilled hands-on digital

messaging support to over 25,000 national and international users. Oversaw

maintenance, troubleshooting, security, reporting, repair and updates.

Identified problems and provided timely resolution by proactively

supervising all mail queues. Established domain and address blocking and

address rules on SMTP gateways.

. Executed and managed migration and upgrades from Exchange 5.5 to

Exchange 2003 and Active Directory. This was done once Active

Directory was established in the network, an Active Directory

Connector was installed and the Exchange 2003 servers were built.

Mailbox moves were performed using the Exchange Task Wizard. 25,000

user and functional business mailboxes were migrated.

. Built and configured Exchange 2007 servers with roles including Client

Access Server, Hub Transport Server and Mailbox Server. Migrated a

group of 2,000 test mailboxes from Exchange 2003 to Exchange 2007.

Test migrations were done using both the Exchange Task Wizard and

Quest Exchange Migration Wizard. Also tested migrations from Lotus

Notes to Exchange 2003 and 2007 using the Notes Migrator for Exchange

from Quest.

. Architected a virtual environment of Exchange servers using VMware.

This included server specifications such as CPU size, RAM, disk

carving, and processor capacity. Multiple tests were performed to

test a mixed mode environment of Exchange 2003 and 2007 servers.

. Supervised safe and efficient migration of Exchange servers to new

data center location. This was done with the installation of 4

"swing" Exchange servers as users were moved to these "swing" servers

when their original home server was scheduled to be moved to the new

data center. These moves were all done transparent to the users and

very limited down time was noticed as all moves were conducted off-

hours. Once the original servers were racked in their new data center

location, the user mailboxes were moved back to their original

servers. This project also allow for user to perform some database

cleanup as we were able to free up some white space to allow for

better performance.

. Conducted extensive testing of Exchange replication and failover to DR

site. 2 servers were built with identical specs and one was shipped

to our DR site to act and the DR server for the master server in our

production site. Replication was performed using WanSynchHA. Once

the data from the master server was completely replicated and the

appropriate DNS modifications were made, a switchover was performed.

The DR server became the master server and performed with normal

functionality. Multiple rounds of testing were performed both before

and after the switchover.
