其实最想要的是保留project配置，这样客户端的DSN配置统统不用改，报错数据倒是可以不要。
有文章已经给出了配置迁移教程：https://medium.com/@avigny/sentry-on-premise-migration-dc0e42f85af4
不过我在过程中遇到了奇怪的错误

仔细看原来是导出的sentry_export.json文件混入了其他的stdout内容：
07:14:23 [WARNING] sentry.utils.geo: settings.GEOIP_PATH_MMDB not configured.

把这些多余的行删除后，才成为合法JSON数据。
然而继续执行又遇到了sql错误：

我一开始想删JSON里的数据，比如(sentry, groupresolution)，搜索groupresolution可以找到对应的对象。可是删了几十条，还是报错，没见有结束的迹象……
换个思路，我把新sentry的数据库清了吧。先找到postgresql对应的容器id，docker exec -it <container_id> bash进入，psql -U postgres到数据库shell，然后`TRUNCATE TABLE django_content_type`
又报错：
postgres=# TRUNCATE TABLE django_content_type;
ERROR: cannot truncate a table referenced in a foreign key constraint
DETAIL: Table "django_admin_log" references "django_content_type".
HINT: Truncate table "django_admin_log" at the same time, or use TRUNCATE ... CASCADE.
外键约束。。。那没办法了，直接TRUNCATE TABLE django_content_type CASCADE;
NOTICE: truncate cascades to table "django_admin_log"
NOTICE: truncate cascades to table "auth_permission"
NOTICE: truncate cascades to table "auth_group_permissions"
TRUNCATE TABLE
再次导入，成功了。
