One Good option that came out from Jonathan Update is to create new tablespace
and using CTAS with parallel DML to add 6 new table in this tablespace and then
move with TTS. Any expert view as this might be better way

JonathanYes it was also one of the good options but as the tablespace is big
file with multiple other objects and so is the reason, I didn't list in my
options. Definitely, if someone has used it and even it needs some downtime to
copy the file can be a better option than other options, then can give a try.
Our tablespace is currently 25 Tb that contains most of the required 6 tables
that need to be copied of which only 2 are more than 2 TB and rest are few
Gigs.

Any scope for using transportable tablespaces ?
Even if you have to transport more than you want then drop the excess objects
after the tablespace(s) arrive.

Subject: Copy Big Table from one Db to another
Did anyone has done any benchmark and has created any details on the best
method to copy a big table from one DB to another. I am looking for a 2-5 Tb
tables to be moved within the same ASM storage or can say that these different
databases share the same ASM disk group. Some options like
1. expdp/impdp - with optimization like parallel or so
2. Using DB Link and Insert Append
3. Using Copy command
4. Using sqlcl or other Oracle tool
Tables have multiple LOBs object and it is not partitioned. Any initialization
parameter setting like increasing PGA for Direct operation or tweak that can
save the time
TIA
Sanjay
