yes
(probably all) migration issues are resolved in getting the server up to 9.2.
To check, review the "Administering SAS Enterprise Guide 4.3" at
http://support.sas.com/documentation/onlinedoc/guide/index.html
In the middle it says "If you are migrating from SAS Enterprise Guide 4.2, the metadata is already in a SAS 9.2 Metadata Repository, so you only need to migrate SAS Enterprise Guide projects."
and
"A utility is included with SAS Enterprise Guide 4.3 to enable you to migrate groups of projects and documents to the correct format and to make global changes to metadata references. For more information, see Using the Migration Wizard." which may be the most important link for you "Using the Migration Wizard"
