The current time machine backup is about 1,7TB and time machine is already delting old files :-/
Is it deleting old backups because it's out of room, or is it doing normal "thinning" of expired backups (it deletes all but the first of the day after 24 hours, and keeps that one for a month. Then it deletes all but one per week.
How old is your oldest backup, and do you really need them to be kept longer? Remember, when TM deletes old backups, it's only deleting it's copies of things you changed or deleted long ago, not the backups of anything that's still on your system.
If you do need them longer, your best bet may be to just leave those backups alone; let Time Machine start fresh on the new drive. You can always see and restore from the old set via the Browse ... option, per Time Machine - Frequently Asked Question#17.
Every time I copy the folder to the bigger disk it gets an error code -8062 and the copy process stops, (been coping then for about 6 hrs, tried it 3 times)
"The operation can’t be completed because an unexpected error occurred (error code -8062)."
The backups are probably damaged, and you can't copy damaged backups. Try to repair them, per #A5 in Time Machine - Troubleshooting.
Look at the new disk; you must delete (or erase) whatever it copied before starting over.
I don't want to reformat the new drive becasue I need to put some stuf from there to the 2TB disk ...
That's not a good idea. If you need to put other stuff on the disk, make a separate partition first, so Time Machine has its own, exclusive space. See Time Machine - Frequently Asked Question#3.
And note that the new drive/partition must be formatted exactly like the old one. If the existing drive is Mac OS Extended (Journaled), the new one must be the same; if it's Mac OS Extended (Journaled, Case-sensitive), you must use that on the new one.
