When migrating from Unity 2.4.6 (WNT4, SQL 7, Exchange 5.5) to 3.1.2b (W2K Server, SQL2000, Exhange 5.5) our main concerns are:<br><br>1- Keep Subscribers DB (keep in mind different unity versions)<br>2- Maintain Windows NT Accounts (keep in mind different O.S.)<br>3- Keep Voice mailboxes<br>4- Maintain Exchange Accounts <br><br>¿Is there a single specific import/export utility taking into account all the different applications?.<br><br>Thanks in advance for your coperation.<br><br>
