Thanks again. Although I think the solution you proposed is the best, I'm not sure if it can be implemented in my environment. As I said in my first question, indexers store the indexes on a NAS via iSCSI connections, which gives me two doubts.
On one hand, I can't create the new indexers with the same configuration as the old ones, because on the NAS I only have two LUNs, each one with an iSCSI connection, so I can't have the new and old indexers connected to the NAS at the same time for replication, and I need that after the migration, the new indexers keep saving the indexes on the NAS. I'm investigating whether it would be possible to resize the current LUNs to create two new ones, and be able to replicate.
On the other hand, due to the way disks are mounted in Windows and Linux, the indexes path would be different in each operating system, but because those paths are defined on the indexes.conf files on the master node, i can't specify the rigth path for each indexer.
Is there any way to set different index paths on each indexers, or to temporarily change the path during migration in order to solve these problems?
Would it be possible to directly connect the new indexers to the LUNs, so that they already have all the indexes without doing buket fixup between the old and new indexers, even if that means stopping data collection for a day or so?
