Piler migration from old server to new server.

[B.JEGADEESAN]

We are synced the below data's from old piler to new piler.

1. store directory synced.
2. database dump and import into new server.
3. sphinx directory synced.

After all the data's are synced and we start the piler service in new piler its started, But while start the searchd we got the following error (/var/piler/sphinx/main1.sph is v.42 (from Sphinx 2.x), binary is v.50; NOT SERVING)

OLD Server packages versions:

‌ Sphinx - 2.3.2 , Piler - 1.3.0

NEW Server packages versions:

‌ Sphinx - 3.3.1 , Piler - 1.4.4

Please guide us how to start searchd with our old server sphinx directory data (without reindex), Because we had store data upto 14TB.

If you don't want to reindex, you need to stick with sphinx 2.
