Hi Vinoth,
Every Hr 1000 tables are getting imorted ? So Import still running I guess. Better be patient I would reccomend , and check tmp directory too, it should increse time by time if import is running .
The error you mentioned is because of duplicate entries and it wont stop your import I feel .
Since export took 6 Hrs , you should expect around 18 Hrs for import from normal experience .
Next time , when you do you can increase the number of parallel processes etc while importing, you cn exclude tables which are not necessary to be a part of export ,update the latest tp & R3trans etc can speed up the process.
