## Export
Deck currently supports exporting all boards a user owns in a single JSON file. The format is based on the database schema that deck uses. It can be used to re-import boards on the same or other instances.
The export currently has some kown limitations in terms of specific data not included:
- Activity information
- File attachments to deck cards
- Comments
-
```
occ deck:export > my-file.json
```
## Import boards
Importing can be done using the API or the `occ` `deck:import` command.
It is possible to import from the following sources:
### Deck JSON
A json file that has been obtained from the above described `occ deck:export [userid]` command can be imported.
```
occ deck:import my-file.json
```
In case you are importing from a different instance you may use an additional config file to provide custom user id mapping in case users have different identifiers.
```
{
"owner": "admin",
"uidRelation": {
"johndoe": "test-user-1"
}
}
```
#### Trello JSON
Limitations:
* Comments with more than 1000 characters are placed as attached files to the card.
Steps:
* Create the data file
* Access Trello
* go to the board you want to export
* Follow the steps in [Trello documentation](https://help.trello.com/article/747-exporting-data-from-trello-1) and export as JSON
* Create the configuration file
* Execute the import informing the import file path, data file and source as `Trello JSON`
Create the configuration file respecting the [JSON Schema](https://github.com/nextcloud/deck/blob/main/lib/Service/Importer/fixtures/config-trelloJson-schema.json) for import `Trello JSON`
Example configuration file:
```json
{
"owner": "admin",
"color": "0800fd",
"uidRelation": {
"johndoe": "johndoe"
}
}
```
**Limitations**:
Importing from a JSON file imports up to 1000 actions. To find out how many actions the board to be imported has, identify how many actions the JSON has.
#### Trello API
Import using API is recommended for boards with more than 1000 actions.
Trello makes it possible to attach links to a card. Deck does not have this feature. Attachments and attachment links are added in a markdown table at the end of the description for every imported card that has attachments in Trello.
* Get the API Key and API Token [here](https://developer.atlassian.com/cloud/trello/guides/rest-api/api-introduction/#authentication-and-authorization)
* Get the ID of the board you want to import by making a request to:
https://api.trello.com/1/members/me/boards?key={yourKey}&token={yourToken}&fields=id,name
This ID you will use in the configuration file in the `board` property
* Create the configuration file
Create the configuration file respecting the [JSON Schema](https://github.com/nextcloud/deck/blob/main/lib/Service/Importer/fixtures/config-trelloApi-schema.json) for import `Trello JSON`
Example configuration file:
```json
{
"owner": "admin",
"color": "0800fd",
"api": {
"key": "0cc175b9c0f1b6a831c399e269772661",
"token": "92eb5ffee6ae2fec3ad71c777531578f4a8a08f09d37b73795649038408b5f33"
},
"board": "8277e0910d750195b4487976",
"uidRelation": {
"johndoe": "johndoe"
}
}
```
