The Connect to source database task in the Data upgrade checklist establishes a connection between the Microsoft Dynamics AX source system database and the target system database. After you make this connection, you can begin preparing the target database for the bulk-copy operation that occurs during data upgrade.
Configure matching user permissions
Windows integrated security is used to connect to the source database from the target system. If the administrative user who is performing the upgrade on the target system does not have access to the source system database, the source system will reject the database connection. Open Microsoft SQL Server Management Studio on the source system and perform the following steps:
Grant Microsoft Dynamics AX database access to a domain user with administrative privileges on the target Microsoft Dynamics AX 2012 system.
Add the user to the db_owner and public roles.
Connect to source database
Complete the following steps:
In the Data upgrade checklist, expand the Data upgrade group.
Click Connect to source database.
In the Connect to source database form, do the following:
In the Server name field, type the name of the server and the Microsoft SQL Server database in the format SERVER\DATABASE.
In the Database field, type the name of the Microsoft Dynamics AX source database instance, for example, DynamicsAX50.
Click OK.
The upgrade framework searches the network for the server and database that you specified. When the computers connect successfully, the Presynchronize task becomes available in the Data upgrade checklist.
