I'm going to be upgrading an old mailman 1.0 install to 2.x

In looking around at our old install I've discovered a lot of old que files in .../mailman/data/ such as

1534 May 25 2001 mm_q.29687.1 1534 May 25 2001 mm_q.29683.1 1532 May 25 2001 mm_q.29660.1 1532 May 25 2001 mm_q.29656.1 1532 May 25 2001 mm_q.29652.1 1532 May 25 2001 mm_q.29631.1 1532 May 25 2001 mm_q.29627.1

Many of these files are three years old. Can I delete this old stuff manually without causing any problems elsewhere?

Thanks for any info you can provide...
