So I went ahead and allowed this to proceed (I’ll look at the errors later), but now I have a very big peculiarity. I had attempted to import these into a folder called “old-yahoo-group” by 1st creating this CATEGORY within the system and then I pushed all of the mbox folders into a folder here:

```plaintext
/var/discourse/shared/standalone/import/data/old-yahoo-group

```

I thought I had understood the instructions such that these messages, upon importation, would show up in the appropriate category, however they’re all hidden in the system.

I can do a search and find old messages just fine, however they do not appear in any aggregate location.

How can se manipulate this last import to go into a defined category such that all ~35k messages show up in a convenient section that indicates these are old messages?

Upon looking further, I appear to have found what happened:

> @gerhard - I was able to migrate an mbox archive of 22,000 messages using this script on a Digital Ocean droplet with only 1GB RAM. No problems. Thank you for the write-up of instructions. Everything worked great. The only mistake I made on my first attempt was trying to name the /var/discourse/shared/standalone/import/data/X subfolder using a new category I created before running the script. That caused the import to place these messages into the Uncategorized category. On second attempt, I del…

Now I need to figure out how to recover from this…

So this worked perfectly (where `old-yahoo-group` had already been created and NO other uncategorized posts existed (and it was actually disabled in the Settings)):

```plaintext
/var/discourse/launcher enter app
rails c
un=Category.find_by_slug('uncategorized')
newcat=Category.find_by_slug('old-yahoo-group')
Topic.where(category_id: un.id).update_all(category_id: newcat.id)

```
