# Check Connectivity

We check if each source can indeed connect to each of its destinations. We measure network speed in the process and estimate transfer time if the *entire media database* in the source were to be migrated to the destination.

### Begin

{% endstep %}

{% step %}

### Copy the Speed Measurement program to the source recorder specified

Ensure that you copy the program to the correct recorder source as specified by the XPort application. **The program won't function on other source recorders.**

{% endstep %}

{% step %}

### Extract and run the program on the source recorder

{% endstep %}

{% step %}

### Wait for Completion

Wait until the program finishes on the specified source recorder. **The program measures the network speed to each destination recorder expected to receive content from the source under consideration.**

{% endstep %}

{% step %}

### Repeat on Other Sources

If there are multiple recording server sources, the XPort wizard prompts the user to repeat the previous steps on each source recorder.
{% endstep %}

{% step %}

### Review Transfer Speeds

After the process is repeated for each source recorder:

1. XPort displays the connectivity status between each unique source-destination pair.&#x20;
2. XPort displays network speed measurement for media transfer between each unique source-destination pair.&#x20;
3. It also shows the estimated transfer times if the entire media database were to be transferred. Currently, there is no API support for XPort to estimate times for only a few cameras and/or within a specific time window.
4. Use the numbers shown below as a rough estimate. You can input the measured network speed figures into the Migration calculator for a more precise time estimate. [Media Migration Calculator](https://vega25.com/xport/xport-media-migration-estimator/)

Then, click "**>"** in the Wizard to continue.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vega25.com/xport/user-manual/upgrade-everything-workflow/step-by-step-user-guide/media-migration/check-connectivity.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
