### Re-import OAI with clean index
After the upgrade is complete, re-index all items into OAI with a clean index:
```console
$ export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx2048m"
$ dspace oai -c import
```
The process ran out of memory several times so I had to keep trying again with more JVM heap memory.
### Processing Solr Statistics With solr-upgrade-statistics-6x
After the main upgrade process was finished and DSpace was running I started processing the Solr statistics with `solr-upgrade-statistics-6x` to migrate all IDs to UUIDs.
## statistics
First process the current year's statistics core:
```console
$ export JAVA_OPTS='-Dfile.encoding=UTF-8 -Xmx2048m'
$ chrt -b 0 dspace solr-upgrade-statistics-6x -n 2500000 -i statistics
...

```
After several rounds of processing it finished. Here are some statistics about unmigrated documents:
- 227,000: `(*:* NOT id:/.{36}/) AND (*:* NOT id:/.+-unmigrated/)`
- 471,000: `id:/.+-unmigrated/`
- 698,000: `*:* NOT id:/.{36}/`
- Majority are `type: 5` (aka SITE, according to `Constants.java`) so we can purge them:
```console
$ curl -s "http://localhost:8081/solr/statistics/update?softCommit=true" -H "Content-Type: text/xml" --data-binary "<delete><query>*:* NOT id:/.{36}/</query></delete>"
```

After some time I got an error about Java heap space so I increased the JVM memory and restarted processing:
```console
$ export JAVA_OPTS='-Dfile.encoding=UTF-8 -Xmx4096m'
$ chrt -b 0 dspace solr-upgrade-statistics-6x -n 2500000 -i statistics-2018
```
Eventually the processing finished. Here are some statistics about unmigrated documents:
- 365,473: `(*:* NOT id:/.{36}/) AND (*:* NOT id:/.+-unmigrated/)`
- 546,955: `id:/.+-unmigrated/`
- 923,158: `*:* NOT id:/.{36}/`
- 823,293: are `type: 5` so we can purge them:
```console

### Processing Solr statistics with AtomicStatisticsUpdateCLI
On 2020-11-18 I finished processing the Solr statistics with solr-upgrade-statistics-6x and I started processing them with AtomicStatisticsUpdateCLI:
```
$ chrt -b 0 dspace dsrun com.atmire.statistics.util.update.atomic.AtomicStatisticsUpdateCLI -t 12 -c statistics
```
