Merging mongodb files in different location

May i know how do i merge my mongodb data files?

The following is my current situation:

At /data/db:

drwxr-xr-x 3 root root      4096 2011-03-15 06:38 .
drwxr-xr-x 3 root root      4096 2011-03-15 00:35 ..
-rwxr-xr-x 1 root root         5 2011-03-15 06:54 mongod.lock
drwxr-xr-x 2 root root      4096 2011-03-15 00:43 social_scraper
-rw------- 1 root root  67108864 2011-03-15 06:39 social_scraper.0
-rw------- 1 root root 134217728 2011-03-15 06:38 social_scraper.1
-rw------- 1 root root  16777216 2011-03-15 06:39 social_scraper.ns

At /var/lib/mongodb : 

drwxr-xr-x  5 mongodb mongodb      4096 2011-03-15 07:06 .
drwxr-xr-x 46 root    root         4096 2011-03-10 09:40 ..
-rwxr-xr-x  1 root    root            0 2011-03-15 07:06 mongod.lock
drwxr-xr-x  2 root    root         4096 2011-03-15 07:06 social_scraper
-rw-------  1 root    root     67108864 2011-03-15 07:06 social_scraper.0
-rw-------  1 root    root    134217728 2011-03-15 07:06 social_scraper.1
-rw-------  1 root    root     16777216 2011-03-15 07:06 social_scraper.ns

How do i merge all of the records into /data/db or /var/lib/mongodb ?

The above records ( in both directories ) have been restored using mongod --repair

It will be great if specific steps can be given as I am quite a newbie when it comes to MongoDB maintainence.

I'm using ubuntu 10.04 server edition, MongoDB v1.6.5.

Best Regards.

You can use mongodump to move files from first database in bson files, and than use mongoimport to import dumped files into another database:

mongodump.exe --host localhost:27020 --db dbName

mongorestore.exe --host localhost:27020 --db secondDBName folderWithBsonFiles
