Resolving upgrade issues

What you need to know  

Every Data ONTAP release family has unique requirements concerning upgrades. Before you decide whether to upgrade, you should understand

• Issues you must resolve before upgrading to the new release
• New system behavior after upgrading to the new release

Because significant new features are introduced in each new Data ONTAP release family, you might encounter issues when upgrading to a new release family, especially if you are not upgrading from the immediately previous version of Data ONTAP.

For example, if you are upgrading from a release in the 6.2 family to Data ONTAP 6.4.5, you must review and resolve upgrade issues associated with the 6.3 and 6.4 release families (but not 6.2 or earlier) before upgrading to 6.4.5.

For more information, see Appendix C, Understanding Release Family Upgrades.

The following sections discuss upgrade issues and new system behavior associated with release families:

• Upgrading to Data ONTAP 6.4 or later
• Upgrading from releases earlier than Data ONTAP 6.3
• Upgrading from releases earlier than Data ONTAP 6.2
• Upgrading from releases earlier than Data ONTAP 6.1
• Upgrading from releases earlier than Data ONTAP 5.3
