Hi, CarmenHui
Thanks for your post, and welcome to the MYOB Community Forum.
The date when you have been upgraded depends on your account or serial number. As there will be an exact date when it was upgraded. Regarding your concern about annual leave entitlements of your employees, kindly send us the screenshot of the employee's annual leave entitlement set up and kindly make sure to include the anniversary date of the employees.. Also, if you have the leave report prior to the upgrade. Make sure to remove any sensitive information before posting in the Forum.
We are looking forward to your response.
Best regards,
Doreen
