Update to The Latest Version

In this section:

Update with Data Preservation

To update FindFace Enterprise Server SDK to the latest version while maintaining face data, do the following:

1. Stop all the FindFace Enterprise Server SDK services:

   sudo service 'findface*' stop
   sudo service 'fkvideo*' stop
   sudo service 'ntls' stop
   sudo service 'nginx*' stop
   sudo service 'tarantool*' stop
   sudo service 'mongod*' stop
   

   Note

   Starting with version 2.6, the nnapi component is deprecated, and extraction-api is used as a default facen extractor (as well as a default face detector). If you update from a nnapi-based version, install extraction-api after this step and then remove nnapi. It is important that you do so, minding the sequence, otherwise you can accidentally remove some important data.

   sudo apt-get update
   sudo apt-get install findface-extraction-api
   sudo apt-get remove findface-nnapi
   

2. Prepare the new package on each designated host.

3. Upgrade the services by executing:

   sudo apt-get update
   sudo apt-get upgrade
   

   Tip

   Be sure to check configuration files after this step.

4. Start the FindFace Enterprise Server SDK services.

   sudo service 'findface*' start
   sudo service 'fkvideo*' start
   sudo service 'ntls' start
   sudo service 'nginx*' start
   sudo service 'tarantool*' start
   sudo service 'mongod*' start
   

5. Migrate FindFace Enterprise Server SDK to a different detector or neural network model if necessary.

Reinstall in Full

To fully reinstall FindFace Enterprise Server SDK, do the following:

1. Remove the old instance with all the enrolled faces.
2. Deploy the latest version, following the standard deployment procedure.
