As stated above . I upgraded IQ from 15.4 to 16 sp10 .
Post upgrade :
0) alter database upgrade .
1) Run sp_iqcheckdb (verify , allocation ,check)
2) took full backup of database
3)added -iqlm in cfg file
4)started IQ server in normal mode
Question : I have not changed any of following db options . Do i still need to rebuild index (sp_iqrebuildindex) .....
FP_NBIT_IQ15_Compatibility
CREATE_HG_WITH_EXACT_DISTINCTS
REVERT_TO_V15_OPTIMIZER
Appreciate your recommendation ... it is approx 15 TB database size .

Ajay Pandey
