Limitations

• Migration of older version of EFA to newer version of EFA is similar to adding devices to newer fabric and configuring fabric. If there are no changes in fabric configuration, devices migrate to the newer version of EFA successfully. Limitation on pre-validations and post-validations apply. Similar limitations apply to fabric configured through CLI or out-of-band means.
• As part of pre-validations, ASN, IP address of interface, loopback interface IP, and MCT VE IP validations are done. Other pre-validations mentioned in Pre-validation of Configuration are NOT handled.
• Post-validation is NOT handled.
• If you enter a fabric name that already exists with added devices, import fails.
• If the existing fabric type mismatches with the fabric to be imported, import fails.
• If the fabric name entered is “default” and import fails, the fabric properties rollback to the original state.
• Non-Clos Embedded fabric import is not supported.
• If the user explicitly changes the device credentials which are not in-sync with Embedded fabric database, the device registration fails.

The following are not supported:

• Devices with preexisting configuration and configured through out-of-band means such as CLI and not through Embedded fabric.
• Devices configured through Embedded fabric and firmware upgraded to SLX 20.1.1 and later releases containing simplified MCT feature. Import fails if you perform firmware upgrade before importing. Import the fabric first and then perform firmware upgrade.
