# CLIO MIGRATOR (ONE OFF!)
|
|
|
|
This tool is a (really) hacky way of migrating some data from
|
|
[clio](https://github.com/XRPLF/clio) due to the [specific pull request
|
|
313](https://github.com/XRPLF/clio/pull/313) in that repo.
|
|
|
|
Specifically, it is meant to migrate NFT data such that:
|
|
|
|
* The new `nf_token_uris` table is populated with all URIs for all NFTs known
|
|
* The new `issuer_nf_tokens_v2` table is populated with all NFTs known
|
|
* The old `issuer_nf_tokens` table is dropped. This table was never used prior
|
|
to the above-referenced PR, so it is very safe to drop.
|
|
|
|
This tool should be used as follows, with regard to the above update:
|
|
|
|
1) Stop serving requests from your clio
|
|
2) Stop your clio and upgrade it to the version after the after PR
|
|
3) Start your clio
|
|
4) Now, your clio is writing new data correctly. This tool will update your
|
|
old data, while your new clio is running.
|
|
5) Run this tool, using the _exact_ same config as what you are using for your
|
|
production clio.
|
|
6) Once this tool terminates successfully, you can resume serving requests
|
|
from your clio.
|
|
|
|
|
|
## Compiling
|
|
|
|
Git-clone this project to your server. Then from the top-level directory:
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
cmake --build . -j 4
|
|
```
|
|
|
|
Once this completes, the migrator will be compiled as `clio_migrator`. Then
|
|
you should copy your existing clio config somewhere and:
|
|
```
|
|
./clio_migrator <config path>
|
|
```
|
|
|
|
This migration will take a few hours to complete. After this completes, it is optional to perform a database verification to ensure the fields are migrated correctly, by running:
|
|
```
|
|
./clio_verifier <config path>
|
|
``` |
