Upgrading to 64-bit FortiWLC-50D/200D/500D
FortiWLC release 8.6.0 onwards only 64-bit OS is supported on FortiWLC-50D/200D/500D hardware controllers. If you are upgrading to the current release from pre-8.6.0, perform this procedure to migrate from 32-bit to 64-bit OS.
Note: Disable NPlus1 prior to performing this procedure.
- Download the FortiWLC 64-bit migration image file, for example forti-8.6-0build-2-x86_64- rpm.migration.tar.fwlc.
- Run the upgrade controller command to install the image.
- Log into the controller using the existing username and password.
-
After successful migration, upgrade the controller using the upgrade-image command (same as the existing 64-bit FortiWLC-1000D/3000D upgrade procedure), for example, upgrade-image scp://@:/- rpm.tar.fwlc both.
Note: After migration/upgrade to 64-bit OS, downgrading to a previous version is not supported.
