It depends on your scenario. So which product are you using and which HANA feature do want to use? You can use this blog to start answering this questions: HANA 1.0 vs HANA 2.0

There is a blog for that:

Covers tenant databases, XS advanced, and the new tools.

Simply put, the main difference are all the new features added since the release of SAP HANA 2.0 SPS 00: persistent memory, active/active read-enabled system replication, Fast Restart Option, data masking and anonymization, user groups, ... (the list is long).

Hana 2.0 is being hailed by SAP as the latest platform for digital transformation.

sap hana 2.0 is an offering that leverages cutting edge data management and database technology.
Data Encryption Comparison between HANA 1.0 and HANA 2.0

SAP HANA is designed to copy data from memory to disk at periodic save points and also captures every data change in redo log entries. This makes sure that the database can be restored to its latest committed state post failure. It has to be stated that, the above mentioned data will stay unencrypted on the HANA server disk and is supposed to be saved from unauthorized access at the operating system level from perspective of security. It is in this stage that encryption is employed.

A Direct comparison between SAP HANA 1.0 and 2.0 SPS 00 is given in the table below

Service Pack Feature HANA 1.0 SPS12 HANA 2.0 SPS00 Cryptographic Service Provider required Yes Yes Data Volume Encryption Yes Yes Encryption Keys stored in SSFS Yes Yes Renewal of (Page) Encryption Keys recommended Yes Yes Redo Log Encryption No Yes Memory Encryption No No Backup Encryption No No Database Trace Encryption No No Root Key Backup possible/required No Yes Root Key Password possible No Yes Import of root key e.g. after disaster recovery No Yes

Major Differences between SAP HANA 1.0 and SAP HANA 2.0:

The most remarkable feature of HANA is that redo log encryption is possible. Post activation, log entries undergo encryption using a 256 bit long root key. This key can be considered as another key for data volume encryption and must also be maintained separately. Users have to remember that there is the distinct possibility and or need to back-up encryption root keys with HANA 2.0 for example in the case of redo log encryption.

Such a root key back-up may be required for recovery when it comes to a disaster scenario. If the root key back-up is lost, then it may lead to a situation where the data is unrecoverable. Hence it is recommended to perform a root key backup at periodic intervals. If users lose the root key then it may lead to a situation where the data is unrecoverable. While carrying out root key back-ups are highly recommended, this leads to the requirement of a new root key backup, every time the root key is changed. Along with this, a password will secure the changing root key, and the required password is supposed to be set before the root key back-up is executed.

Conclusion

SAP HANA has always been recognized as the leader in database management systems and as database servers. While SAP HANA 1.0 has a strong set of core features, SAP HANA 2.0 builds on these great foundation features with superior sets of enhancements in everything from data management and advanced analytical processing to Application development and tool enhancements.

what are the impact will be there after upgrading from Hana 1.0 to Hana 2.0.

With the release of HANA 2.0 SPS 02 database and the fact that HANA 2.0 is mandatory for S/4HANA 1709 release, many customers who are embarking on S/4HANA journey will be faced with the task of upgrading their current HANA 1.0 database to HANA2.0.

For HANA 2.0, there are minimum operating system and hardware requirements that needs to be fulfilled. These changes may require a OS and/or Hardware upgrades based on your current infrastructure. Recently, I had to recommend Hardware and OS upgrades to a customer, who was running their HANA 1.0 DB on an Intel Ivy Bridge based hardware and old OS version. They were planning to upgrade S/4HANA 1610 to S/4HANA 1709 which required HANA 2.0. These upgrades, if necessary, will add additional time to the overall project and it’s recommended to plan so that minimum requirements can be completed in time before the actual database upgrade. Also with HANA 2.0, Multitenant Database Containers (MDC) are mandatory staring with HANA 2.0 SPS01. So, when upgrading to HANA 2.0 SPS01 or higher, if your HANA 1.0 is a single-DB system, then the upgrade will automatically migrate the single-DB to MDC.
