Upgrade from ICM 6 to 7 (TR) -- Domain conversion tool / UMT

Question

Hi, we are currently upgrading from 6 to 7.0 and subsequently to 7.5 (TR, new hardware, new domain, new instance).  So far we've staged our W2k3 domain and all the other soon to be ICM servers.
I'm currently trying to migrate the domain users and it tells me that I need to use the Domain Conversion Tool to go migrate the domain users from 6 to 7. (Staging guide chpter 4)
I can't find any documentation on the Domain Conversion Tool, when I run the executable I can see the different triggers (below) but that's it.
I've done an export and gotten a file but what next?
Do I do a convert now?
is the convert going to change my production database?
I'm also reading that the Domain Conversion Tool was replaced by the UMT (for 7.0 to 7.+).
Or should I now use the UMT and point it to my export file?
Im afraid to run the convert and and messing up my Rogger sideA database?
Has anybody use this tool?
any tips and or documentation is appreciated.  Thanks
D:\ciscoutils\domainCnvTool>domcvt
The syntax of this command is:
DomCvt.exe /DB:dbname /F:filename /M:mode [/OD:old domain name]
          [/ND:new domain name][/P:password]
   /DB:dbname           Specifies the database name to operate on (e.g. cust1_sideA)
   /F:filename          Specifies the full path of the file to import or export to
   /M:mode              Indicates export mode or convert mode
                         E  Export mode
                         C  Convert mode
The following switches are only needed in Convert Mode:
   /OD:old domain name  Specifies the old domain name to convert from in NetBIOS form (e.g. MyDomain)
   /ND:new domain name  Specifies the new domain name to convert to in NetBIOS form (e.g. MyDomain) or DNS form (e.g. MyDomain.mycompany.com)
   /P:password          Specifies the default password to be set for all the users in the new domain
Use quotation marks when there are spaces in the file name or password

Hi,
From the 7.x(y) Staging Guide:　
Common Steps Required before Migrating any ICM ComponentOn the Domain Controllers:
Confirm that Domain Controllers have been upgraded from NT Domain to Windows 2000Active DirectoryOn the CallRouter Server:
　\RouterA\Router\CurrentVersion\Configuration\Global\DBMaintenance.
Note:
If moving a CICM with SideA and SideB disable the Configuration changes on bothsides.
On the Logger server:　
Copy the Domain Conversion Tool (DomCvt.exe) from the ICM 5.0(0) or ICM 6.0(0) Third-PartyTools CD as applicable (Domain Conversion Utility folder) onto the Logger server.
Export the ICM user list using the DomCvt tool using the following command:
domcvt /DB:<instancename>_sideA /F:c:\DomConvert\userlist.txt /M:E.
And then lower down in the guide:
On the Logger server:
Step 18
Run the Domain Conversion Tool to convert the ICM users exported earlier, using the followingcommand:
domcvt /DB: <instance_name>_sideA /F:c:\DomConvert\userlist.txt /M:C /OD:<old_domain_netbios_name> /ND: <new_domain_netbios_name>Note: You can use the /p option to create a global password. If you do not use the /p option,the password is reset to null.
I'm looking to run this myself shortly. The only caveat with this info is that its extracted from the section related to ICM5 and migration from multiple to single forest ... so possibly not the correct info. However, there's not much documentation on this as you've seen!
