Hi,

Thank you for you your replies. I took a snapshot of the server before I 
started the upgrade process. I will roll back to the snapshot and follow the 
process Cyrus has detailed. Before I do so, would you be able to comment on the 
process I followed and the error I encountered -

1)      Upgrade Yarn and Node.js to 1.13.0 and 10.15.2 respectively (this 
brings the versions of this software up to the same level as the our other 
working 4.4.1 environments)

2)      python -m pip install --upgrade pip

3)      pip install arches==4.4.1 --upgrade --no-binary :all: (this completed 
successfully, upgrading directly from 4.1.1)

4)      python manage.py migrate – (errors encountered) – is this due to a lack 
of memory on the server? – (see final error massage - 
django.db.utils.DatabaseError: out of memory for query result)

the latest 4.4.2 version)

Hi Tom -

One of the challenges for upgrading from 4.1.1 will be upgrading your 
project(s). This is because at version 4.2 we switched from Bower to Yarn for 
js dependencies because bower was getting deprecated. As Adam has mentioned, 
each version of Arches has the upgrade process outlined in the release notes: 
https://github.com/archesproject/arches/tree/master/releases.  You could go 
from version to version following the upgrade instructions for each version. 
Alternatively, you could try the process below which is a bit shorter. I test 
the upgrade from version to version with each release, so it should go 
smoothly. I haven't tested the shortcut process below, but I think it should be 
fine. In either case, there are quite a few steps going from 4.1 to 4.4, so I 
would recommend creating a database backup and web server snapshot (if 
possible) before getting started.

1. upgrade to version 4.3.1:


pip install arches==4.3.1 --upgrade --no-binary :all:

pip uninstall pycryptodome, rdflib-jsonld

pip install pycryptodome django-oauth-toolkit==1.1.2 PyLD[requests]==1.0.3 
pyprind==2.11.2



python manage.py migrate

python manage.py es delete_indexes

python manage.py es setup_indexes

python manage.py es index_database

2. follow the project upgrade steps in the 4.2.0 release notes starting with 
the yarn install:

https://github.com/archesproject/arches/blob/master/releases/4.2.0.md#installing-yarn

3. Then follow the project upgrade steps for version 4.3.1:

https://github.com/archesproject/arches/blob/master/releases/4.3.1.md#upgrading-an-arches-project

4. Upgrade to version 4.4.1:


pip install arches==4.4.1 --upgrade --no-binary :all:

python manage.py migrate

python manage.py es delete_indexes

python manage.py es setup_indexes

python manage.py es index_database

5. Then complete the project upgrades for 4.4.1:

https://github.com/archesproject/arches/blob/master/releases/4.4.1.md#upgrading-an-arches-project

Hope that helps and that your upgrade goes smoothly. Let me know if you have 
any questions.

- Cyrus

Hi Tom, one other thought, sometimes I like to just create a brand new virtual 
environment and install the new version in there, leaving the existing on as 
is. Then you can switch which environment is used by your app in your apache 
config (if that's how you're serving it), etc, and you can switch back if 
something goes wrong with the pip installation process (which, frankly, is 
unlikely).

As for other actions to take, it's possible you will need to run migrations in 
your project. I'd recommend looking back through release notes for the 
incremental versions between 4.1.1 and 4.4.1, which can be found on this forum.

Hi Tom,
The pip command to install a specific version should be this `pip install 
myPackage=={version num}
So for Arches that should be:

‘pip install arches==4.4.1 --upgrade --no-binary :all:’

Hi,

We have an Arches deployment at 4.1.1, I wish to upgrade this environment to 
4.4.1 (not the latest 4.4.2 release).


1)      Can you advise on the specific command to do this since ‘pip install 
arches --upgrade --no-binary :all:’ will install 4.4.2

2)      Are there any other steps that I will need to take when upgrading from 
4.1.1 to 4.4.1

Many thanks
