Before you start: migrate from Redis Cloud to KiviDB

Check what the database uses

The console shows the version, the memory used, and (on the database page) Advanced Capabilities when search, JSON, time series or probabilistic are on. From a client:

redis-cli -h redis-12345.c12345.us-east-1-mz.ec2.cloud.rlrcp.com -p 12345 \
  --user default --pass "$REDIS_PASSWORD" INFO server | grep redis_version
redis-cli ... MODULE LIST
redis-cli ... DBSIZE

Add --tls --cacert redis_ca.pem if TLS is on.

To find which keys are of a module type, count types over a sample:

redis-cli ... --scan --count 1000 | head -100000 | \
  xargs -n 100 sh -c 'for k; do printf "TYPE \"%s\"\n" "$k"; done' sh | \
  redis-cli ... | sort | uniq -c

ReJSON-RL is JSON, TSDB-TYPE is time series, and MBbloom--, MBbloomCF, CMSk-TYPE, TopK-TYPE and TDIS-TYPE are the probabilistic types. (The command above breaks on key names with spaces or quotes; it is for a quick look.)

Check	Why it matters
Time series keys	An RDB containing them is refused as a whole; copy them over commands with RIOT
Probabilistic keys	KiviDB has no Bloom, Cuckoo, Count-min, Top-K or t-digest commands: rebuild those in your application, or keep them elsewhere
Search indexes	Not in a backup: list them with FT._LIST and save each definition (FT.INFO) so you can run FT.CREATE again
Lua (EVAL, EVALSHA, FUNCTION) in your code	KiviDB needs the lua or full build; on Cloud, turn on Lua scripting when you create the database
TLS, mutual TLS	The tls or full build; on Cloud, turn TLS on (and client certificates if you used mutual TLS)
ACL users and roles	Recreate them in KiviDB
Eviction policy	Set the same one in KiviDB; KiviDB's default is noeviction
Active-Active	Copy over commands; see Active-Active

Size it

The database's Metrics tab shows Used memory, and Pro databases show Memory used under Performance. Size KiviDB from the peak, with headroom. KiviDB Cloud seeds a database from a file only when the file is no larger than the database.
