Domestic Helper Visa Questions

Good day!

 

I went to immigration today to transfer my visa to my new passport.

 

I am just confused now because i will travel on June 2019.However,the information told me that there’s no need to transfer the visa.  Just carry the the old and new passport if i will travel.

 

My visa will expire on September 26,2019.My old passport will expire on October 26,2019.Can you give me a confirmation about my situation?is it still ok to travel?

 

I'm a domestic helper here in HK.

 

Thank you
