HR asking infi docs before offer letter

Cleared all rounds and feedback was great, before releasing offer letter, HR sent an email asking for lot of documents - current company’s offer letter, increment letter, other offer letters that I hold, resignation acceptance letter citing last working date, etc.
is this normal?

Pretty normal. For me the red flag is asking folks who are not freshers for their 10th,12th marksheets (instead of just bachelors and masters degree certificates)
