solr - 从 Apache Solr 4.7.2 直接升级到 Apache Solr 7.6 的问题？

Question

我有一个基于 Apache Solr 的项目，我想将版本从 4.7.2 升级到 7.6，我参考文档https://github.com/cominvent/solr-tools/tree/master/upgradeindex升级索引从 4.7.2 到 5 并得到以下输出。

我不知道如何处理输出。您能否请有人向我建议一个指导方针，以进一步将整个 Solr 索引升级到更高版本。

./upgradeindex.sh -t 5 /home/solr
Target version is 5
