We currently run our Magento stores on 1.9.4. It is time for us to upgrade but our hosting company tells us we are not able to install Magento 2.4.0 due to the fact that it requires a CentOS 7 Upgrade (we currently only have CentOS 6 running) saying:
"...versions of Elasticsearch higher than 6.X cannot run on the same due to the highest available version of glibc on CentOS 6. With the above in mind, we recommend first upgrading your server to a CentOS 7 and then we can install Elasticsearch version 7.X on the same."
There are 2 big questions here:
- If we upgrade to CentOS 7 - are we going to be able to run Magento 1.9.4 and 2.4.0 side by side given the different requirments?
- Would we be able to install and run Magento 2.3.5 on CentOS 6? and is this preferable over Magento 2.4.0? We are not likely to upgrade Magento for a while so maybe it would be best to start with the highest version currently available? (2.4.0)
