Hi Manas,
Above example command can do the long2lob conversion and the migration from old to new TS.
This command converts only uncompressed tables of given tablespace.
You should execute next command (Given below) to migrate the data of remaining tables (compressed)
brspace -u / -f tbreorg -a long2lob -s <Source TS> -t allsel -n <Target TS> -I <Target Index TS> -c ctablobind -lc medium -ic sap_proc -l 2 -p 16 -KST
As I mentioned in my last update, you should run all of the above commands in sequence to migrate the whole data to new tablespace, so that each command can migrate selective data from old to new in phases.
Since it's an online activity, you should not bother about the execution time.
Run this migration with minimum additional load so that migration cannot hamper your system performance.
Anther question if database size is 7 TB how long time required from transfer data from old to new tablespace?
Execution time depends on the resources that you have on system. As I said, you should not bother about the execution time.
