Upgrading from releases earlier than Data ONTAP 6.4

Information about the Data ONTAP 6.4 release family you should know

The following sections discuss upgrade issues that you should be aware of if you are upgrading from releases earlier than Data ONTAP 6.4.

Macintosh resource.frk files affected

If your storage system is accessed by Macintosh computers using the DAVE^TM client from Thursby Systems, the DAVE client starts using the new streams feature when Data ONTAP 6.4 or later is installed. Information that was stored in special resource.frk files is lost. To solve this problem, you should run the na_macstream conversion utility from a Windows client after the upgrade is completed and before DAVE clients access any files. For instructions about obtaining, installing, and running the na_macstream utility, see Appendix B, DAVE Macintosh Client resource.frk Conversion.

Space reservation settings

If you are using space reservations with Data ONTAP 6.3, space reservations on volumes are ignored when you upgrade to later versions of Data ONTAP. Space reservations are turned on for all logical unit numbers (LUNs) and virtual local disks (VLDs), but are left off for all other files.
