# FHIR versions

Formbox module supports FHIR versions 4.0.0 to 5.0.0. FHIR version used is taken from the Aidbox. (Data can be stored only on that version)

However, you can load/import questionnaires with FHIR versions ranging from 3.0.0 to 5.x. Our module automatically checks the Questionnaire version and handles conversion as needed.

### FHIR Version configuration

To configure Aidbox FHIR version you can read [Bootstrap FHIR package list](https://www.health-samurai.io/docs/aidbox/reference/all-settings#bootstrap-fhir-packages) section.

### Import/load questionnare with conversion

* `Load Questionnaire` can be done through `Form Builder UI > 3 dots menu > Load`
* `Import` can be done via - `Form Templates Page > Create template > Import Quetionnaire`

If Questionnaire's version differs from Aidbox's - you will be notified about this and conversion will be made.

### WARN: some data may be lost due conversion

Because of versions incompatibility - some data may be stripped out.

#### 5.x.x -> 4.x.x

* `Questionnaire.copyrightLabel`
* `Questionnaire.versionAlgorithm[x]`
* `Questionnaire.item.optionsConstraint = 'optionsOrType'`

#### 3.x.x -> 4.x.x

* `Questionnaire.item.answerOptions.[valueUri/valueAttachement]`
