Migrating from Asana to Jira - tips?

[sheer]

I'm aware that Jira has stopped supporting a built in import tool for issues from Asana so I'm left with the CSV option.

I got that covered but where I'm still hurting are the attachments and comments.

Comments I can live without, but attachments are a deal breaker.

I don't see any easy way for doing this.

Any tips from whomever went through this would be highly appreciated.

Many thanks!
