Olá!  
Alguém já tentou migrar do NodeBB 4.9.x mais recente para o Discourse dev atual?

```plaintext
/home/dev/discourse/script/import_scripts/nodebb/mongo.rb:100:in 'NodeBB::Mongo#post': undefined method '[]' for nil (NoMethodError)

      post["timestamp"] = timestamp_to_date(post["timestamp"])
                                                ^^^^^^^^^^^^^
        from /home/dev/discourse/script/import_scripts/nodebb/mongo.rb:95:in 'block in NodeBB::Mongo#posts'
        from /home/dev/discourse/script/import_scripts/nodebb/mongo.rb:95:in 'Array#map'
        from /home/dev/discourse/script/import_scripts/nodebb/mongo.rb:95:in 'NodeBB::Mongo#posts'
        from script/import_scripts/nodebb/nodebb.rb:413:in 'block in ImportScripts::NodeBB#import_posts'
        from /home/dev/discourse/script/import_scripts/base.rb:943:in 'block in ImportScripts::Base#batches'
        from <internal:kernel>:168:in 'Kernel#loop'
        from /home/dev/discourse/script/import_scripts/base.rb:942:in 'ImportScripts::Base#batches'
        from script/import_scripts/nodebb/nodebb.rb:412:in 'ImportScripts::NodeBB#import_posts'
        from script/import_scripts/nodebb/nodebb.rb:52:in 'ImportScripts::NodeBB#execute'
        from /home/dev/discourse/script/import_scripts/base.rb:47:in 'ImportScripts::Base#perform'
        from script/import_scripts/nodebb/nodebb.rb:568:in '<main>'

```

Estou com esse erro ao migrar no ambiente de desenvolvimento.  
Alguma ideia?

Os scripts de migração ainda são suportados pela Comunidade em 2026?  
O campo **timestamp** existe e contém dados válidos

Obrigado.
