Migrating model references from Enabler to SQL Server
You can retain old model references such as bookmarks and OSLC links. Use the Mappings.ini file to map model references from an Enabler database to a SQL Server database.
To map old model references, perform the following:
For a Standalone installation
1. Create a Mappings.ini file in the ModelerATFiles folder. The folder resides in following location:
C:\ProgramData\PTC Integrity Modeler\ModelerATFiles
2. For each database, create a mapping entry using the following format:

[MAPPINGS]
<old-server>\<old-repository>=<new-instance>\<new-database>
<old-server>\<old-repository2>=<new-instance>\<new-database2>
<old-server>— specifies the name of the old Enabler server.
<old-repository>— specifies the name of the old repository.
<new-instance>— specifies the name of the new SQL Server instance in the following format: <machine-name>@<instance-name>
<new-database>— specifies the name of the new database.
For a Client/Server installation
1. On the Integrity Modeler server, create the Mappings.ini file in the ModelerATF share folder.
2. Create a mapping entry for each database reference using the same format as a Standalone installation.
Enabling mapping logs
You can enable logs for reference mapping. To enable logs, do the following:
1. Start the Registry Editor.
2. In the left pane, expand HKEY_CURRENT_USER > Software > ARTiSAN Software Tools > SFC2.
3. Under the SCF2 subkey, create a DWORD (32-bit) value with the name LogMappings and set it to a number other than 0.
The mappings are logged to the ModelerMappings.log file in the Windows temporary folder: %temp%.
