Do we need to mention iManager for DNS Migration??
Prior to performing a migration, review TID 7004455. This TID lists recommended pre-check tests to perform to increase the likelihood of a successful iPrint migration. It also contains useful troubleshooting information in the event of a problem. The iPrint Migration tool copies an NLM (psminfo.nlm) from the OES 2 SP1 server to the NetWare server. The NLM is loaded on the NetWare server. The NLM reads the NetWare Print Manager database ([vol]:/ndps/xxxxxxxx.psm/psmdb.dat) and creates a text output of the database attributes and values (psmimport.xml). The printer drivers associated to the NetWare printer agents are copied to the Linux server and uploaded to the Driver Store repository using an iPrint Linux command line tool (iprntman). The /opt/novell/iprint/bin/psmimport.xml is executed using iprntman. iprntman creates the printer agents and their attributes defined in the XML file. As the iPrint migration tool heavily relies on iprntman, it is recommended to test iprntman's ability to authenticate prior to the migration. See TID 7004455 for important iPrint Migration Pre-check steps to increase the probability of a successful migration. Whether the iPrint migration succeeds or fails, users will continue to print to the source server. To test the success or failure of an iPrint migration, go to the /ipp page on the destination server (http://[IPorDNSofDestinationServer]/ipp and install printers.
See TID 7004109 to understand why the Consolidate migration is preferred over the Transfer-ID method when iPrint is involved. The TID also shows how to safely perform a Transfer-ID migration after the iPrint service has been migrated using the Consolidate method. Create target printer objects in the Source Printer Context An option within the iPrint Migration is to “Create target printer objects in the Source Printer Context”. Creating a new object (iPrint Linux Printer Agent Object) in the same context as the NetWare Printer Agent Object with the same name is not possible. Because of this, this option will rename the NetWare Printer Agent Object to have an _NW extension to the eDir name. By renaming the NetWare Printer Agent object, workstations pointing to that NetWare object will still be able to print. The iPrint client is not aware of the eDir name, instead, it prints to the printer object in the MOD. The name in the MOD does not change when using this feature. If the iPrint Migration does not succeed, but the migration went far enough to create the /opt/novell/iprint/bin/psmimport.xml file, you can run this command while in the /opt/novell/iprint/bin directory to complete the migration: iprntman psm –xml-import ./psmimport.xml
