Will it use the first full backup or the second full backup for scheduled incremental backup in this case?

Hello,

I have made a manual full backup and then I create a task to schedule daily incremental backup automatically. So now, I have the full backup+day1 incremental, day2 incremental, day3 incremental....

A few months later, I decide to make a full backup manually again. When the schedule task is running the next day, will the scheduled daily incremental backup that I created earlier on use the new (second) full backup as the "base" or will is still use the old (first) full backup and as the base?

Thanks
