I grew up with my 7th standard date of the birth certificate as my only original proof of birth and when I applied for a job in England and need health care registration, I had major issues as my initials were not fully mentioned in some and some certificates the full stop was missing between my name and initials. Luckily the passport entry was correct.
I had to delay joining abroad as it took me 6 weeks to first make a request, sign an affidavit, the apply to the university where I had to run pillar to post to get it authorised as it was 6 years old and finally got the certificates re-issued, Then the next issue was funnier, I had to re-submit all my corrected certificates to three authorities as my first set of documents (based on which the job was given) were now invalid.
My sincere advice is, please do the necessary changes in the format approved, check with your university and often speaking to the office clerks over a cup of coffee gives you the right information as they would have handled many such cases. Lastly, if you are considering a passport, please do not apply before these changes are actually made and accepted.
