Re: Migrate from C* 2.1.11 to 3.9 (max version I can find in docker hub)

Hey Jeff,

Thanks a lot. Biggest change I have my mind is using
TimeWindowCompactionStrategy  in our timeseries tables (currently we use
SizeTieredCompactionStrategy).

We already have data in those tables (6 nodes each with 250GB and timedout
data but didn't get deleted from the disk) and do you think its safe to do
the migration just by changing the table property ?

I couldn't find a migration strategy for TWCS from STCS.

BTW, thanks for the great work with TWCS.

Should be the same as going to 3.0, no file format version bumps between 3.0 
and 3.9

 

(There was one format change in 3.6 – CASSANDRA-11206 should have probably 
bumped the version identifier, but we didn’t, and there’s nothing special you’d 
need to do for it anyway.)

Hi Users, 

 

I am trying to find a migration guide from 2.1.* to 3.x and figured I should go 
through the NEWS.txt so I read that and found out few things that I should be 
careful/consider during the upgrade.

 

I'm curious there's any documentation with specific steps how to do the 
migration. 

 

Anyone finished a successful migration from 2.1.* to 3.x (x > 8). Any warnings 
or red lights I need to be considered ?

 

Regards

Lahiru

Hi Users,

I am trying to find a migration guide from 2.1.* to 3.x and figured I
should go through the NEWS.txt so I read that and found out few things that
I should be careful/consider during the upgrade.

I'm curious there's any documentation with specific steps how to do the
migration.

Anyone finished a successful migration from 2.1.* to 3.x (x > 8). Any
warnings or red lights I need to be considered ?

Regards
Lahiru
