migrating from 1.x to 2.x

[kaveh minooie]

me again,

is there anyway that I can import my existing crawldb from a nutch 1.4 
which has about 2.5 B (with a B) links in it and currently resides in a 
hdfs file system into webpages table in hbase?


and what happened to linkdb in nutch 2.x?

thanks,
