# Offline update

Systems without Internet access can't update Itgrix module using `/opt/itgrix_<crm>/update.sh` script. Use offline update procedure instead:

1. Download the update file onto a PC with Internet access.
2. Transfer the downloaded update file to the server where you have the Itgrix module installed.
3. Run the update.

## Download update file

### Via online interface

At <https://itgrix.ru/offline_updates/> you can get the module updates through the online interface.

Select appropriate options and click "Download updates". The update file will be downloaded onto your computer.

### Using terminal

The update file can can be downloaded by making a request to `https://bx24asterisk.ru/api/v3/get_offline_update.php` with the following options:

* **`crm`** - short name of your CRM:
  * `bx` for itgrix\_bx (Bitrix24);
  * `amo` for itgrix\_amo (Kommo, former amoCRM);
* **`arch`** - short name of the processor architecture:
  * `i386` for 32-bit processors based on the architecture x86 (including i586, i686 and others);
  * `amd64` for 64-bit processors based on the architecture x86-64 (also known as x64, Intel 64, AMD64 and others);
* **`version_from`** - the currently installed version, e.g. `3.5.0`;
* **`version_to`** - target version, **not mandatory:** if not specified, the current latest version will be used; you may need to specify it if you upgrade to a supported, but not the latest version:
  * [Change log (new versions) itgrix\_bx](/changelog-bx.md) - for Bitrix24;
  * [Change log (new versions) itgrix\_kommo](/changelog-kommo.md) - for kommoCRM.

{% hint style="info" %}
The file size depends on the number of milestones needed to upgrade from `version_from` to `version_to`.

Archives with these intermediate versions will be included in the update file (but NOT all intermediate versions will be added, but only those necessary for a correct update).
{% endhint %}

#### Examples

Module itgrix\_bx (Bitrix24) has version 3.5.0 installed on 64-bit server, need to update **to current latest version.** Download the update, for example, using `curl`:

```bash
curl -OJL "https://bx24asterisk.ru/api/v3/get_offline_update.php?crm=bx&arch=amd64&version_from=3.5.0"
```

If you need to get an update **only to version 3.5.3**, then specify the parameter

`version_to=3.5.3`:

```bash
curl -OJL "https://bx24asterisk.ru/api/v3/get_offline_update.php?crm=bx&arch=amd64&version_from=3.5.0&version_to=3.5.3"
```

## Installing the update

After downloading the update file, you need to transfer it to the server where you have Itgrix module installed.

{% hint style="info" %}
The update file is a self-extracting archive in the form of a shell script.

Example: `itgrix_bx-amd64-update-v3.5.0_to_v3.5.3.sh`
{% endhint %}

All you need to do to install the update is run the file **as root or with sudo**:

```bash
sudo bash <path>/itgrix_bx-amd64-update-v3.5.0_to_v3.5.3.sh
```

The update process is similar to online update (via script `/opt/itgrix_<crm>/update.sh`), but does not require downloading intermediate versions and other information - everything you need is already contained in a self-extracting archive.

{% hint style="success" %}
Update completed.
