+
+- The indexes on AReS are messed up again
+ - I made a backup of the indexes, then deleted the `openrxv-items-final` and `openrxv-items-temp` indexes, re-created the `openrxv-items` alias, and restored the data into `openrxv-items`:
+
+```console
+$ elasticdump --input=http://localhost:9200/openrxv-items --output=/home/aorth/openrxv-items_mapping.json --type=mapping
+$ elasticdump --input=http://localhost:9200/openrxv-items --output=/home/aorth/openrxv-items_data.json --limit=1000 --type=data

+$ elasticdump --input=/home/aorth/openrxv-items_data.json --output=http://localhost:9200/openrxv-items --limit 1000 --type=data
+```
+
+- Then I started a fresh AReS harvest
+
+## 2021-04-26
+
+- The AReS harvest last night seems to have finished successfully and the number of items looks good:
+
+```console
+$ curl -s http://localhost:9200/_cat/indices | grep openrxv-items
+yellow open openrxv-items-temp H-CGsyyLTaqAj6-nKXZ-7w 1 1 0 0 283b 283b
+yellow open openrxv-items-final ul3SKsa7Q9Cd_K7qokBY_w 1 1 103951 0 254mb 254mb
+```
+
+- And the aliases seem correct for once:
+
+```console
+$ curl -s 'http://localhost:9200/_alias/' | python -m json.tool
+...
+ "openrxv-items-final": {
+ "aliases": {
+ "openrxv-items": {}
+ }
+ },
+ "openrxv-items-temp": {
+ "aliases": {}
+ },
+...
+```
+
+- That's 250 new items in the index since the last harvest!
+- Re-create my local Artifactory container because I'm getting errors starting it and it has been a few months since it was updated:
+
+```console
+$ podman rm artifactory
+$ podman pull docker.bintray.io/jfrog/artifactory-oss:latest
+$ podman create --ulimit nofile=32000:32000 --name artifactory -v artifactory_data:/var/opt/jfrog/artifactory -p 8081-8082:8081-8082 docker.bintray.io/jfrog/artifactory-oss
+$ podman start artifactory
+```
+
+- Start testing DSpace 7.0 Beta 5 so I can evaluate if it solves some of the problems we are having on DSpace 6, and if it's missing things like multiple handle resolvers, etc
+ - I see it needs Java JDK 11, Tomcat 9, Solr 8, and PostgreSQL 11
+ - Also, according to the [installation notes](https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace) I see you can install the old DSpace 6 REST API, so that's potentially useful for us
+ - I see that all web applications on the backend are now rolled into just one "server" application
+ - The build process took 11 minutes the first time (due to downloading the world with Maven) and ~2 minutes the second time
+ - The `local.cfg` content and syntax is very similar DSpace 6
+- I got the basic `fresh_install` up and running
+ - Then I tried to import a DSpace 6 database from production
+- I tried to delete all the Atmire SQL migrations:
+
+```console
+localhost/dspace7b5= > DELETE FROM schema_version WHERE description LIKE '%Atmire%' OR description LIKE '%CUA%' OR description LIKE '%cua%';
+```
+
