We're currently trying to do an in-place upgrade from AEM 6.2 to 6.4 on our Dev environment. There is an issue that we are facing during the repository migration using the Crx2Oak command. Please find below the command used for migration and the error thrown. Please help me in resolving this issue.
You are hitting the limit of the number of files a process can open.
In case you are working on Linux: use "ulimit -n" in the same shell to display the number of files you are allowed to open. Please consult the documentation of your linux distribution how to increase it permanently.
