VM to UM; exchange 5.5 to exchange 2K migration

i've the following setup:

-existing mail server= exchange 5.5 clustering

-existing domain= win nt4 domain

-no AD available

-unity 3.1(3) - license for UM

-exchange 5.5 on unity run as VM only for now

-unity joined existing domain

-no connector between exchange 5.5 on unity and existing exchange 5.5 clustering

we plan to migrate the setup above to the following:

-new domain= win 2k domain with AD

-new mail server= migrate exchange 5.5 clustering to exchange 2k clustering

-unity will become domain member

question: what is the best solution for the exchange installation and migration in the new setup?


-disconnect unity with exchange 5.5

-upgrade exchange 5.5 to 2k on the unity

-re-connect unity with exchange 2k

-build connector between exchange 2k on unity and the new exchange 2k clustering to run UM


-disconnect unity with exchange 5.5

-restore exchange 5.5 on unity data to the new exchange 2k clustering

-install exchange 2k admin software on unity

-use the new exchange 2k clustering as UM


-any idea?

pls help and many thanks in advance.

Re: VM to UM; exchange 5.5 to exchange 2K migration

Is the Exchange 5.5 cluster and Exchange 5.5 installed on Unity in the same Exchange 5.5 organization? If not, is your plan use the Exchange Server Migration Wizard which can help you to consolidate multiple Exchange 5.5 organizations?

Re: VM to UM; exchange 5.5 to exchange 2K migration

the exchange 5.5 cluster and exchange 5.5 installed on unity are in the different organization. there is no plan to consolidate the current multiple exchange 5.5 organization.

however, we do have plan to upgrade the exchange 5.5 to exchange 2000.

hence, what is the best option to have the unity UM with the exchange 2000?

a. multiple exchange 2000 organization

b. single exchange 2k organization in cluster mode

c. or any other option
