Is it be possible to direct new R20 Sysview online history collection to existing like R19 VSAM files from prior releases? Is it correct that in case of  fall back from R200 to R190, some new record data will be discarded - but otherwise no restrictions ? 


Component: CIDB


IDB2 history files are upward compatibles but not downward compatible. It means after upgrading to R20 from R19 and for some reason there arises a  need to fallback to R19 the same R20 files can't be  used in R19.
