# Migration from water-meter „old“ to water-meter “AI-on-the-edge-device”

There are only some few steps necessary to migrate your old system to the new one.

Please follow the following steps:

#### 1. Follow the installation guide to flash the ESP32CAM and prepare a SD-Card with the content of the master

#### 2. Save the following files from the old Docker system on your PC:

- Reference Points 1-3 (only 2 needed)
- `Config.ini`

#### 3. Copy Reference Points 1-3 onto the new water-meter system (Directory `/config`)

Please note only two Reference Points are supported in the new system.

#### 4. Open new `config.ini` File:

Insert from the old `Config.ini` file `[alignment]` and `[alignment.ref0]` and `[alignment.ref1]` section the two Ref x and y position and the `initial_rotation_angle= 123`into the new `Config.ini` File, e.g.:

###### Old:

    [alignment.ref0]
    image=./config/RB01_65x65.jpg
    pos_x=28
    pos_y=63

    [alignment.ref1]
    image=./config/RB02_50x35.jpg
    pos_x=497
    pos_y=127

    [alignment]
    initial_rotation_angle=180

###### New:

    [Alignment]
    InitalRotate=180
    /config/RB01_65x65.jpg 28, 63
    /config/RB02_50x35.jpg 497, 127
    SearchFieldX = 20
    SearchFieldY = 20

#### 5. Insert the old Digit Values into the new `Config.ini` File, e.g.:

###### Old:

    [Digital_Digit.ziffer1]
    pos_x=265
    pos_y=117
    dx=28
    dy=51

    [Digital_Digit.ziffer2]
    pos_x=310
    pos_y=117
    dx=28
    dy=51

    [Digital_Digit.ziffer3]
    pos_x=354
    pos_y=117
    dx=28
    dy=51

    [Digital_Digit.ziffer4]
    pos_x=399
    pos_y=117
    dx=28
    dy=51

    [Digital_Digit.ziffer5]
    pos_x=445
    pos_y=115
    dx=28
    dy=51

###### New:

    [Digits]
    Model=/config/dig0630s3.tflite
    ;LogImageLocation = /log/digit
    ModelInputSize 20, 32
    digit1, 265, 117, 28, 51
    digit2, 310, 117, 28, 51
    digit3, 354, 117, 28, 51
    digit4, 399, 117, 28, 51
    digit5, 445, 115, 28, 51

#### 6. Make sure that you have the same quality and size settings as in your old `Config.ini`

In the old configuration this was coded in the html-string for the image source:

###### Old:

    URLImageSource=http://IP-ADRESS/capture_with_flashlight?quality=5&size=VGA

Default was Quality=5 and VGA.

###### New:

    ImageQuality = 5
    ImageSize = VGA

#### 7. Repeat the same for the analog section

#### 8. Insert your SSID and Password into the new wlan.ini File

#### 9. Compare and edit [ConsistencyCheck] Section with new [PostProcessing] Section

#### 10. Save new config.ini File in the new System.

#### 11. Restart the system.

#### 12. After the first start set manually the PreValue in the new system
