Hi,
I am planning to upgrade Exchange 2003 Standard to Exchange 2003 Enterprise edition due to limitation of 75GB Information store. I would like an expert opinion/input who actually did this upgrade and have hand-on experience. I have few concerns:

- Do I need a product key in hand for exchange 2003 ent
- Is there any unknown issues after or during upgrade
- Any upgrade requirements for existing symantec anti-spam and mail security
- Is Backup required for re-cycle after upgrade.
- Any other advise.....
Thanks in advance....
Sean

see http://www.petri.co.il/upgrading_from_exchange_server_standard_edition_to_the_enterprise_edition.htm
1) its been a long time since ive used 2003, but i dont remember it ever needing product keys
2) your asking if there are any unknown issues.... ummm, you may want to reconsider that question
3) I dont believe so
4) im not sure what your asking there, but your should take a full backup both before and after the upgrade

if upgrading is on the cards, wait 2 months and go straight to 2010....

Whether you need keys depends on how Exchange was purchased.
If it was purchased through a volume programme then no keys will be required.
If you have a retail box set then a key will be required.

After reinstalling Exchange you will need to reinstall Exchange 2003 SP2 and then all of the post SP2 updates. Nothing else should need to be changed because the product is effectively the same.

Thanks for you reply,
We have corporate environment means we installed 2003 Std under volume License agreement. So this will be inplace upgrade?
   
we have SOW ready for migration to exchange 2007 but it may take few weeks to start migration the interim solution is to migrate to exch 2003 Ent, having said and we extremely running out space on exchange store.

We have 2003 AD, I haven't considered yet for Exch 2010 also I haven't explore the requirements of Exch 2010 with 2003 or 2008 AD domain.
Cheers

Wasn't the reference to your existing installation, but your new installation. Whether you need a key depends on what you are installing instead.

We are going to upgrade with Enterprise 2003 under VL. also I forgot to mention that we have BES v4 running as well. Any effect on BES?

Thx

You will have to reprov BBs since cross forest migration.

If you are simply upgrading the existing server from standard to enterprise then the BES is unaffected - other than being unavailable for a time while you do the update.

Not sure what the above post is about considering I don't see any reference to a cross forest migration.
