Rollback from 6.5 to 5.5

[aloksinghk]

Hi All,

I have upgraded my ESXI and vCenter from 5.5 to 6.5, After upgrading to ESXI 6.5.0 build no. 5310538 I have applied a security patch which upgrade the ESXI to 6.5.0 build no 7388607. 

So, is it possible I can roll back to ESXI 5.5 again? As I know I can rollback to previous version only that would be 6.5.0 build no. 5310538.

Thanks

Hello,

You can go only one step back if the configuration is available using Shift + R option during boot process. If you want to go back, only way I can think is to reinstall 5.5

thanks,

MS
