Hi Sergio,
This is just my opinion here
Because the DMA process is so key to the overall migration, I
would start over with the DMA 7.1(3) version. The pain of
scheduling another "maintenance window" to re-run DMA may
be well worth it vs the pain of an unsuccessful upgrade. You may want
to open a TAC case to verifiy the data integrity if you don't start over.
The release notes for DMA do indicate these notes related to the
"Major" CUCM version requirement;
Use this document if you are running supported versions of Cisco Unified CallManager and are ready to upgrade to Cisco Unified Communications Manager 7.1(1x). The DMA version number that you use must match the major version of Cisco Unified Communications Manager. [For example, if you were upgrading to Cisco Unified Communications Manager 7.0(1a), you could use DMA Release 7.0(1) or DMA Release 7.0(1a).]
Tip If you have installed an (a), (b), (c), (and so on), version of Cisco Unified Communications Manager, you only need to match the DMA major version number. For example, if you had Cisco Unified Communications Manager Release 6.1(1b), you could use DMA Release 6.1(1a).
So it depends on what is considered a "Major" version here.
The other things to consider here, are the Bug caveats fixed in DMA 7.1(3);
Caveats That Are Resolved in Data Migration Assistant 7.1(3)

If you do decide to remove the DMA 7.1(2) version, here are the steps;
Removing DMA
You must remove DMA and the applications that are installed with it before installing another DMA version. See the following sections for instructions:
•"Stopping DMA" section
•"Uninstalling DMA" task
Note To uninstall previous versions of DMA, refer to uninstall instructions in the guide for that release. This section applies only to uninstalling DMA 7.1(2).
Stopping DMA
Ensure that DMA is not running on your system. DMA, a server application that is controlled through a browser interface, can continue to run after you close the browser. To verify that you have stopped DMA, perform the following procedure:
Procedure
Step 1 Choose Start > Programs > Cisco Data Migration Assistant> Cisco DMA.
Step 2 When prompted, log in as the Windows Administrator.
The Security Alert window displays. To continue running DMA, you must click Yes.
The Data Migration Assistant Home window displays.
Step 3 If you are running DMA on a secure server, the Warning - Security window displays. It asks whether you want to accept a certificate from the secure server to exchange encrypted information.
To continue running DMA, you must click either Yes or Always. If you click Always, this window will not display again when you access this server.
The Data Migration Assistant Home window displays.
Step 4 From the Data Migration Assistant menu bar, choose Export > Export Data.
The Export Data window displays.
Step 5 Click the View Status link.
Step 6 Review the status to determine whether the last execution completed.
If you are not sure whether the DMA process completed, you can cancel the DMA operation by choosing Start > Programs > Cisco DMA > Cancel Export. The system could require several minutes to cancel the export process.
Step 7 Continue the DMA removal, as described in the "Uninstalling DMA" section.
Uninstalling DMA
Note To uninstall previous versions of DMA, refer to uninstall instructions in the guide for that release. This section applies only to uninstalling DMA 7.1(2).
To uninstall DMA, follow these steps:
Procedure
Step 1 Choose Start > Settings > Control Panel > Add/Remove Programs.
Step 2 From the Add/Remove Programs Window, choose Cisco Data Migration Assistant.
Step 3 Click Remove.
Step 4 Choose Yes to uninstall.
Step 5 Make sure that a restart of the server is possible and choose Yes to restart the server.
Note If you use Virtual Network Computing (VNC) to access your server, you may want to remotely restart the server by choosing No and restarting the server by using the VNC facility that sends Ctrl-Alt-Delete to the server.
