it is worth adding that you can easily export those too.
from the menu:
Wallet > Labels > export (and then import later the same place)
it will create a simple JSON file containing all the addresses that have a label.
{
    "bitcoin_address_here": "Label_data_here",
    ...
}

for the history (transactions) you will have to export them separately:
Wallet > History > export
this is also a simple JSON file that can be used later.
[
    {
        "date": "date_here",
        "label": "Label_data_here",
        "value": "amount_here",
        "txid": "txid_here"
    },
...
]
