In order to align with the naming conventions introduced in https://jira.camunda.com/browse/OPT-4571 the update scripts and the folder containing them (./upgrade) should be renamed from upgrade.sh to update.sh. The folder containing them should also be renamed from ./upgrade to ./update.

AT:

• The update scripts and their containing folder has been renamed
• Doc references have been renamed as well

Hint:

• this is a breaking change to potential existing customer setups and would need to be communicated well if done
