Unclear about one mandatory document

[RWA1]

Hi,

I hope to submit my ILR under Tier 2 soon.

Under the mandatory documents I need to provide, the following is listed

For the period before you were granted leave as a Tier 2 migrant, documents showing that you met the relevant requirements of the immigration rules.

I'm not sure what documents they're asking for. Are they asking for all of the documents I submitted as part of student visa, post-study work visa?

Would appreciate the advice

Thanks

It is mostly for those combining Tier 1 (not PSW) with Tier 2 to make up 5 years.
