+## `The extension is upgraded. However, the index files is outdated.`
+
+You may see this error if you upgrade the extension. On this condition, you should follow these steps:
+
+* Delete the old index folder.
+
+You can delete the folder with this command:
+
+```shell
+rm -rf $(psql -U postgres -tAqX -c $'SELECT CONCAT(CURRENT_SETTING(\'data_directory\'), \'/pg_vectors\');')
+```
+
+If you are using Docker, you can just delete `pg_vectors` folder under the volume directory too.
+
+You need to restart PostgreSQL.
+
+* Reindex.
+
+You can list all indexes that needed to be reindexed with this command:
+
+```sql
+SELECT
+    I.oid AS indexrelid,
+    I.relname AS indexname
+FROM pg_index X
+     JOIN pg_class I ON I.oid = X.indexrelid
+     JOIN pg_am A ON A.oid = I.relam
+WHERE A.amname = 'vectors';
+```
+
+If you get the result like this:
+
+```
+ indexrelid | indexname  
+------------+------------
+      17988 | t_val_idx
+      17989 | t_val_idx1
+      17990 | t_val_idx2
+      17991 | t_val_idx3
+```
+
+You will reindex them with this SQL:
+
+```sql
+REINDEX INDEX t_val_idx;
+REINDEX INDEX t_val_idx1;
+REINDEX INDEX t_val_idx2;
+REINDEX INDEX t_val_idx3;
+```
