To copy blocks from a tape with 1KB blocks to another tape using 2KB blocks, type:
dd if=/dev/rmt0 ibs=1024 obs=2048 of=/dev/rmt1
rgds,

dd if=/dev/rmt0 ibs=1024 obs=2048 of=/dev/rmt1

In fact it is better to use tcopy (if both drives are on the same server as you have here) because tcopy will automatically copy all "tape files" from source to dest tape.
dd will stop at the first tapefile mark.
If you have multiple images on one tape (e.g. an mksysb tape), you would need several dd commands, and use the non-rewinding drives rmt0.1 and rmt1.1 to position the drive at the next tape file after each dd process.
