Jonathan Sinovassin-Naïk commented on UNOMI-867:
------------------------------------------------
h2. Aditionnal information:
Because of this bug, the past events on the profiles will not be updated. In
Unomi 2.5 we changed the format of the pastEvent data to avoid mapping
explosion on elasticsearch. The systemProperties.pastEvents became a nested
property.
Without the modification of the pastEvent property, the profiles will not be
found correctly in the segments having conditions on pastEvent property. Also
the personalization having conditions on the pastEvent won't be resolved
correctly
> Fix reIndex in migration to allow to call the method multiple times

> In the migration we are checking if a script has already been executed before
> executing it.
> It allows to rerun the migration if it failed and start when it failed.
> But there is an issue with the reIndex step.
> If we reIndex the same index in two different scripts, only the first reIndex
> is taken into account.
> because in both cases, the name of the tasks will be
> {code:java}
> index-prefix_index-name(clone creation)
> index-prefix_index-name (recreate the index and perform the re-indexation)
> index-prefix_index-name (delete clone)
> index-prefix_index-name(refresh at the end)
> {code}
> The names should be unique to allow to execute the reIndex several time
> during the migration.
> There is the issue for the profile reindex
> We execute a reIndex in
