Thanks so much . I was using bullzip What I felt with Bullzip was it is good for less amount of data. I have 2 tables each of which has 2.5 million records. For me it is taking for ever, The job that I set up has been running since 12 hours.
I appreciate if you could share the VBA code that you were mentioning. I would love to use that to make the data transfer faster Regards On Thu, Jun 2, 2011 at 9:32 AM, Thomas Harold <thomas-li...@nybeta.com>wrote: > On 5/25/2011 3:42 PM, akp geek wrote: > >> Dear all - >> >> I would like to know if any one has migrated database from >> MS access to Postgres .
