Upgrade from a previous release¶
CAPE Sandbox grows fast. In every release, features are added, fixed and/or removed. There are two ways to upgrade your CAPE: start from scratch or migrate your “old” setup. The suggested way to upgrade CAPE is to start from a fresh setup because it’s easier and faster than migrating your old setup.
Upgrade starting from scratch¶
To start from scratch you have to perform a fresh setup as described in Installation. The following steps are suggested:
- Back up your installation.
- Read the documentation shipped with the new release.
- Make sure to have installed all required dependencies, otherwise install them.
- Do a CAPE fresh installation of the Host components.
- Reconfigure CAPE as explained in this book (copying old configuration files is not safe because options can change between releases).
- If you are using an external database instead of the default or you are using the MongoDb reporting module is suggested to start all databases from scratch, due to possible schema changes between CAPE releases.
- Test it!
If something goes wrong you probably failed to do some steps during the fresh installation or reconfiguration. Check again the procedure explained in this book.
It’s not recommended to rewrite an old CAPE installation with the latest release files, as it might raise some problems because:
- You are overwriting Python source files (.py) but Python bytecode files (.pyc) are still in place.
- There are configuration file changes across the two versions, check our CHANGELOG file for added or removed configuration options.
- The part of CAPE which runs inside guests (agent.py) may change.
- If you are using an external database like the reporting module for MongoDb a change in the data schema may corrupt your database.
Migrate your CAPE¶
The following steps are suggested as a requirement to migrate your data:
- Back up your installation.
- Read the documentation shipped with the new release.
- Make sure to have installed all required dependencies, otherwise install them.
- Download and extract the latest CAPE.
- Reconfigure CAPE as explained in this book (copying old configuration files is not safe because options can change between releases), and update the agent in your virtual machines.
- Copy from your backup “storage” and “db” folders. (Reports and analyses already present in “storage” folder will keep the old format.)
Now setup Alembic (the framework used for migrations) and dateutil with:
pip3 install alembic
pip3 install python-dateutil
Enter the alembic migration directory in “utils/db_migration” with:
cd utils/db_migration
Before starting the migration script you must set your database connection in “cuckoo.conf” if you are using a custom one. Alembic migration script will use the database connection parameters configured in cuckoo.conf.
Again, please remember to backup before launching the migration tool! A wrong configuration may corrupt your data, backup should save kittens!
Run the database migrations with:
alembic upgrade head
Python library upgrades:¶
PIP3:
$ pip3 install -U <library>
- PIP3+git:
- $ pip3 install -U git+<repo_url> $ pip3 install -U git+https://github.com/doomedraven/sflock
