Thank you a lot.
I will perform the operation.
Also I would like to ask if I should truncate those other tables too , if needed. or truncate any other tables that may need to be done ?

truncate table SYS.WRI$_OPTSTAT_HISTHEAD_HISTORY;
truncate table SYS.WRI$_OPTSTAT_TAB_HISTORY;
truncate table SYS.WRI$_OPTSTAT_IND_HISTORY;

As to free space at sysaux as they have huge storage.
Please advice.
Regards,

I had no problems, but you should take a backup before doing it.
