[GitHub] [iotdb] HTHou opened a new pull request #2531: Add the user guide for upgrading v0.11 to v0.12
HTHou opened a new pull request #2531:
URL: https://github.com/apache/iotdb/pull/2531
Update the user guide for upgrading.
<!--
In each section, please describe design decisions made, including:
- Choice of algorithms
- Behavioral aspects. What configuration values are acceptable? How are corner cases and error
conditions handled, such as when there are insufficient resources?
- Class organization and design (how the logic is split between classes, inheritance, composition,
design patterns)
- Method organization and design (how the logic is split between methods, parameters and return types)
- Naming (class, method, API, configuration, HTTP endpoint, names of emitted metrics)
-->
<!-- It's good to describe an alternative design (or mention an alternative name) for every design
(or naming) decision point and compare the alternatives with the designs that you've implemented
(or the names you've chosen) to highlight the advantages of the chosen designs and names. -->
<!-- If there was a discussion of the design of the feature implemented in this PR elsewhere
(e. g. a "Proposal" issue, any other issue, or a thread in the development mailing list),
link to that discussion from this PR description and explain what have changed in your final design
compared to your original proposal or the consensus version in the end of the discussion.
If something hasn't changed since the original discussion, you can omit a detailed discussion of
those aspects of the design here, perhaps apart from brief mentioning for the sake of readability
of this PR description. -->
<!-- Some of the aspects mentioned above may be omitted for simple and small changes. -->
<hr>
This PR has:
- [ ] added documentation for new or modified features or behaviors.
<!-- Check the items by putting "x" in the brackets for the done things. Not all of these items
apply to every PR. Remove the items which are not done or not relevant to the PR. None of the items
from the checklist above are strictly necessary, but it would be very helpful if you at least
self-review the PR. -->
